I will throw in my 2 cents...I have a 2006 Camelot with 2 - 15KW A/C-Heat Pumps and two propane furnaces. I have 2 Zones. I have always been able to set up both the front and rear zone to use the heat pumps and, when it get down to around 33-34 degrees the system will automatically switch over to the two furnaces! These are Dometic replacement units, but I have always had the automatic switch-over feature. It may be the configuration I set up on each A/C unit with the DIP switches on the control boards. I have to be sure I keep the furnace degree set-up lower than the heat pumps or it will cook us out of the coach! Jim G 2006 Camelot TST Rep

For LED Tubes that will work in coaches go to: http://www.ledrvlighting.com/ Click on the "Monthly Specials" link and order the T8 color temp you want. These tubes will work with or without the ballast. They are $15.95 ea... JimG 2006 Camelot

The board is just below the breaker panel. It has a green pilot light on it. The wires from the breakers go into this board then out into the coach to the various items the EMS controls. You have to remove the brown face plate to see the board and connections. JimG 2006 Camelot

The Intellitec board is located in the box where your main 120v breaker panel is. On my Camelot, the board is just below the breaker panel. Take the brown panel off and you will see it below the breaker set up. JimG 2006 Camelot

If your water heater and rear A/C unit is out (which are two items on the EMS system) I would look at the Intellitec board. I had my front A/C go out recently and the EMS display showed everything as OK, all lights green. When I removed the board, I could see the relay for the A/C burned on the circuit board. This has happened to me before as well. I called M & M Electronics (419-965-2662) and spoke with Chris. He confirmed that the board could be bad even though the lights on the display panel are all lighted. I ordered a replacement from them. Once installed, everything was OK. I was told that a 15KW A/C unit is at the high end of the amperage those boards can handle (15 amp) and they will burn out if pushed beyond those limits. It is possible you have two burned relays, one for the A/C and one for the water heater. Worth pulling the board out and looking at the underside to see if there are any burned traces on the board. It will be pretty obvious! JimG 2006 Camelot

One other thing you could check are the breakers in the inverter. There are two on my Magnum inverter. If one or the other trips, it will shut down several AC circuits in the coach. To reset one that has popped out, just push it in. This may be an easy "fix" if the breaker in the inverter just popped! JimG 2006 Camelot

Al, Please don't paraphrase what I said or Mike B said. I said a firmware change was made by the factory and some older TST displays were effected. As we sell more new systems (therefore keeping us in business), the issue can be more pronounced. Most of the people that have this issue recognize that they have gotten a good amount of use out of their system and are willing to update to newer technology at a reasonable price. They purchase a new color or grayscale display which has more innovations than your system. The term "Broke the System" was never used by us! That is your term. In your case, to correct the high pressure readings when you are around a newer system, you will have to update your display. You were told that. Technology marches on in most products and we are no different. I am sorry you are disappointed with your system, but there is a fix for it. I know you want a new display and we did offer that to customers 2-3 years ago for a short time when we were made aware of the intermittent issue. We always try to be aware of the customers needs. If you had called us back then and discussed the issue you were having, we could have helped you. You did not. Now you are on this forum, seemingly trying to turn people against the TST system. In my book that is not a nice thing to do, and yet you still use our system because it is very good! I will not continue to go back and forth on this issue. We both have stated our case. This is my last post on the subject. JimG 206 Camelot

Al ???, This issue occurs with a very small percentage of old displays. To correct the problem (which is a firmware update the pre 2015 monitors do not have) you need a new display, either the grayscale or color. You did not say how old your display is. Newer systems do not have any issues. If you do not want to pay the $86 for a new grayscale display, call me and I will give you a code for a discount on that unit on the TST website. JimG 2006 Camelot

Ed, Our current color display (since the last 1.5 years) will do exactly what you want to do. It has the capability of four (4) trailers, trailers can have different tire pressure settings and there is an automatic feature that will drop all the trailer tires from the screen, except for the unit you are towing. It takes about 15 minutes for this feature to kick in. You can also remove the tow vehicle by pressing the "GO" and the (+) buttons at the same time. You can remove the towed if you push the "GO" and the (-) buttons at the same time. I use it for my towed vehicle all the time, separate from the motorhome. Not sure where you got your information from, but a call to TST Technical Support would have answered your questions. JimG 2006 Camelot

Ward, The battery in the display is promoted as not being user replaceable. That being said, it is plugged into the circuit board so, if you can find a matching battery, it can be changed out. The battery is not something we are going to carry, but I bet if you got the specs off the battery and did a Google search, you would come up with a match. If the incoming power to the display is terminated and the power switch is in the up position, the display will revert to internal battery power. The monitor battery has a long life with no maintenance required. We just provide you with tips to make the system last longer. So far, it has been a non-issue. JimG 2006 Camelot

Ward, What you stated is partially true. Both the grayscale and color displays have lithium batteries and those batteries like to be discharged and recharged for longer battery life. You can absolutely keep the display plugged in if you like. The person you spoke with is incorrect that you would damage the display, but you will shorten the battery life if you keep it plugged in. This is over the course of 5-7 years, not immediately. Any lithium battery left 100% charged will do the same thing, no matter what the application. The advantage of using the display on battery power is the elimination of just one more wire going across your dash to another display. The display will run 7-10 days on a full charge. The "suggestions" are to give you, the customer, the best possible life with the system. If you want to plug it in all the time, that is your prerogative. It will work either way. JimG 2006 Camelot

I guess I am prejudiced but I have been using the TST system for about 12 years and have worked for TST doing Tech Support for the last 6 years. We have a very solid system with almost no errors. The fact you can change the batteries in both the 507 flow-through sensors and the cap sensors keeps the system going a long time. I spoke with a couple of individuals over the last two weeks that have had our system since 2011 and it is still going strong. They just change the batteries once a year. We have newly designed cap and flow-through sensors to keep up with the times and both our color display and grayscale display are a good size for viewing. Of course we have GREAT Tech Support 🙂 and strive to make everyone happy with their TST system. Currently Forest River uses our internal sensors on all of the products they manufacture so that, in itself, is quite a testimony to our product line and its reliability. JimG 2006 Camelot

We have a 3.5 yr old Cricket SX-3 we purchased new. We have carried it around the country in our Saturn Vue. Recently purchased the complete rain enclosure, tinted windshield and a trailer hitch. We are pretty much stationary in Crystal River Florida now and we use the Cricket every day. It has worked well and we are very recognizable in the Park since we have the only Cricket in here. Have had a lot of inquiries so I think another one or two will show up in the near future. I really like the built in charger and the ability to accommodate 4 people on the unit. Works well for us!

So sad to hear Bill passed away. My wife Peggy and I spent some quality time with Bill and Peggy both at their home in Pass Christian and at several Monaco Rallies. Bill was always willing to help anyone for any reason and we will miss him very much. Prayers for Peggy and his family. Rest in Peace Bill!

rpasetto If you have a 510 system, the 507 sensors will not work. As a matter of fact, none of the components are interchangeable. We have not had the 510 system for several years and we are no longer supporting it unless the system is still under warranty. If you have 507 sensors (ones you can change the battery in) the new display will work. It is backwards compatible will any 507 sensor. JimG 2006 Camelot

Batteries for the sensors are an interesting subject. The reason our TPMS batteries now only last between 1.5 and 2 years is that they are constantly transmitting a signal to the display. An OEM system transmits less frequently and can therefore go a much longer time before they have to be replaced. This is why we went from the 510 system, with non-replaceable batteries, to our current 507 system so our customers can replace the batteries and not have to send them in to us. This basically made the 510 system obsolete in a relatively short time. As far as theft goes, we do not see people stealing sensors. If you do not have the rest of the system, they are worthless. Most of the time they are not even noticed on the valve stem. We do provide a sensor "theft deterrent" to help keep honest people honest! Actually, we have had more displays stolen off the dash because they think the display is a GPS unit and rip it off. If the battery is depleted in the sensor, our system does show a warning and the display will beep. We want to let you know that the tire will not be transmitting data and, if a problem occurs with that tire, you will not know it. Very important to replace the battery as soon as possible so you are protected. JimG 2006 Camelot TST Rep

Richard, We are coming out with a visor for the color (or monochrome) display. Tests show that this helps a lot with the screen readability. I believe it will be ready in the next few weeks. Not sure the price, but it will be low. That will help. You can not change the color combination on the display. JimG 2006 Camelot

I would like to reply to several statements since I am the Lead Tech at TST. First, those of you that have our system and it is pre-2016 and you are getting readings of 200-600+ PSI: There was a firmware update in late 2015. Any display manufactured before this update will read those high PSI numbers if the coach gets close to a unit that has one of our newer systems. What happens is the sensors will transmit through the newer repeater and that signal now has the firmware update. The older displays do not know how to interpret the updated signals when they receive them. They then display 200-600+ PSI. There is no way to update the firmware in the older displays. You just have to replace the display with a new color or monochrome unit. They are both backwards compatible with the order sensors. We are no longer giving away displays. That occurred a few times several years ago. The new displays are reasonably priced. There is a manufacturer putting the TST TPMS internal sensors in their units. That is Forest River. They were the first to jump on the bandwagon over a year ago and we are now in many of the towable units. Other manufacturers are now talking with us to outfit their new units. Dynamax is also putting our external sensors on their products. I agree, with a Class A motorhome, it should be a no brainer to include a tire pressure monitoring system in it from the factory as a safety measure! Jim G 206 Camelot TST Rep

Kurt, Is there a way you can run vinegar into the tank and let it stand for a short while? That may get all the smell out of the unit. Be sure to rinse it with fresh water afterwards... JimG 2006 Camelot

Mike, We also worked for a company in Yuma, AZ called RV Decor. The owner was starting to make the MCD style wheel covers a couple of years ago. He had acquired some similar tracks from a plastics supplier. I believe they were a little narrower where the wheel cover went in. You can try calling the owner, Mujeeb Khan, at 928-550-7010. I believe they are closed for the summer but I think the phone rings in to him directly in the summer. He did not continue the venture but he may have some of the plastic track left. Does not hurt to give him a call... Jim G 2006 Camelot TST Rep

Ken, Hope you are well...Since I am the Lead Tech for TST, I would like to help resolve your issue. The first thing I noticed is you said you have your "rear amp" (we call it a repeater) in your bedroom closet. This is probably the worst place to put the repeater, especially if you have a mirror across the closet. It is in a Faraday Cage! I believe if you move the repeater out of the closet and put it into one of your rear bays (where you can find 12v power), your problem should be solved. Give it a shot...

Check out RV Quick Shades from Active RV Upholstery (www.activervupholstery.com). They are internal shades that you custom fit to the windshield and side windows. They come in several colors. Easy to put up and take down. I was hired to do a video on them (which we are producing this weekend) and they seem like a good, economical alternative to the other shades mentioned!

Thanks Jeff...I wondered if that were true! I guess I will crawl under there and see what I can find.

Ivan...I have hydraulic jacks for leveling (Power Gear) and the air dump is a separate system from that. It seems to have one solenoid mounted to the firewall that dumps the air in the suspension system. There is a dump switch on the dash which activates the solenoid. It has worked perfectly for the last 14 years (had to replace the solenoid once) and seems to be a very simple air dump. I can't imagine what would be blocking the air line?? Maybe someone with a 2006 Camelot (or similar) would have encountered this issue. It would be nice to know where this particular air line is coming from before I climb under the coach!
