Yup, 315 all around, you could not easily hurt one of those tires LOL. Surprised your tank was still up front in 2007, maybe it was 2008 when they got the move? Also, I am not sure anything really changed on that front axle between the 2005 and 2007 model other than the extra 500 lbs (or whatever increase it was). Maybe just a tire rating difference? A total wild guess would be in the 300-500 lb range for one less slide. The only real difference would be the small amount of extra framework and fiberglass for the slide itself and some hydraulics. Normally the slide topper would be replaced with just a window awning if the slide was omitted. Cabinets and sofa/chairs would be there regardless. Thanks Paul, Will

Paul, curious how much less your coach weighed with the 3 slide setup instead of the 4 slide setup? 105 PSI sounds low for a 295 steer tire but maybe you were running 315's, I don't recall. I know I am right against my steer axle limit (14500 or 14600, can't remember which). Your 07 would have been a 15100 axle as I recall. Your tank was also moved aft on the 07 model I believe which helps take weight off the steers. WB

Yes. Thanks, I will replace the regulator. It is regulating but something seems off somehow. I did have to install a new solenoid coil on my right tag lower 6 pack valve a few weeks ago as it was not deflating the right bag when raising the tag. Left would deflate but not the right, coil was open. I put a new coil on the old valve body and it works again. I thought maybe that was contributing to my odd numbers but it had no affect. I am not sure why I am lumped into the tire pressure discussion. That was between two other folks.

Sounds like I have a toasted regulator. I will replace it and retry this. Interesting that manual says that to stabilize the pressure, raise the tag using the tag switch for 20 seconds, then reset it and see what it goes to on the gauge. This does not work for me so something is up: file:///C:/Pictures%202023/Motorhome%2005%20C/2005%20Executive%20parts/HWH/Automatic%20Air%20Leveling/tag_axle.pdf

Long read, sorry! I have questions about the tag pressure regulator. My original 2005 regulator was right at the cutoff point when Monaco switched from a 60 PSI unit to a 160 PSI unit. I removed my broken and leaking 60 PSI unit (gauge was broken, regulator leaked) and installed the 160 PSI gauge unit. Took it to the scales, weighed it, adjusted the regulator up a couple of times till I got all the weights where I wanted them. Noted I was at 55 PSI on the newly installed regulator, fully loaded with 10 days of dry camping gear, food, water... This was 2018 and about 60K miles ago. I have had no driving or tire issues however, "every" time I check the regulator it could be at 60-70-80, 40, you just never know. Even if I lift the tag, it will still read whatever it was reading before lifting the tag. The most reliable way to see what it is set at is to dump the suspension down a little then let it relevel itself. As soon as I drive it even .5 miles, it will read some ambiguous number. I try to check it only on level ground. I know Monaco has a proportioning component to the suspension but I am just not clear on how this all works. I presume the regulator is sending air to the tag through another component that proportions whatever pressure was set to eventually get to the tag. The tag tires never look overloaded, flat on the bottom or differently loaded nor does my steer axle. I would think that if the tag actually had 80-90 PSI sent to it that the tag would look more loaded, especially since I only run 85-90 PSI in them. Further when the tag is lifted, the tag bags ARE empty but the regulator will still show whatever it was before lifting the tag so I am sure that number is not in series with the tag bags themselves. I also presume that this is why the 60 PSI regulator/pressure gauge was replaced with a higher capacity unit. There is more but I will stop here for now, hoping someone can clarify how the tag system is ultimately controlled. Thanks you. Will B.

I might be able to come over this weekend if you don't have this taken care of yet. I may (not firm yet) be about 40 minutes from you sometime over the weekend. Maybe Saturday afternoon, late, or possibly Sunday. I checked the campground location, it looks nice there. I know the pre 09 electrical systems much better but if I am that close, might be able to help. Will

I don't recall a swing up door having a safety switch. Seems to me that the safety switches are associated with bay doors under the slide outs. He needs to have it quiet in the coach and push a slide button with someone at the power pack listening for any clicking sounds. If it is clicking, that would tell me the motor may be the issue. If no clicks when activated, it is a control circuit issue. The click is not going to be loud so they may need to be very close to it with the step cover removed. Of course, a Volt meter is better but you have to know how and where to use it. Will

Everyone you drive by thanks you for not straight piping it :-) Will

Wow, congratulations on what I think is a great coach! My 05 Exec is different than yours but I would not sell mine for $80K I am a little surprised at the comments about the 3000 hour generator being higher time. I am more concerned with low time units than I would be a 3000 hour diesel Onan. It might need a set of brushes installed about now and maybe a fan belt but beyond that, should be good to go a very long time. You can put both the brushes and belt on yourself. I would rather have the ISM-11 (which I think this coach has) than the ISX. Well done, great find! Will B.

Dave, Can you disconnect the wire going to the #2 pin (shore or generator power) and the pin 4, ignition wire leaving just the battery boost function in tact for emergency use? I ask as when switching the House batteries to Lithium, the BB relay is supposed to be disabled since we typically use lead acid for starter batteries... Or is there another better way to provide boost for emergency use only with the currently installed system?
