I had pieces of debris in both the regulator and the city water selector. When turning on an inside facet the pressure was good for a few seconds and then reduced to low flow.

Michelin, Toyo, Continental, and BF Goodrich get high ratings from the RV folks. Some of the offshore brands are getting good reviews. I would avoid the Michelin XRV as they had sidewall cracking issues. Also, the Goodyear G670 tires had issues with blowouts.

Many of us have learned to service the Aqua Hot ourselves. There are several YouTube videos as well as posts on this forum. Order the fuel filter and nozzle. Watch the video's. The first time go slow and allow about 2 hours. After that you can do it in 20 min. Good luck finding someone to work on your HWH air ride system. Almost any truck repair facility can repair air suspension systems, but they dislike working on motorhomes. HWH is located in Moscow Iowa. With an appointment they perform suspension service at the factory or you can contact one of their distributors. https://server51.hwhcorp.com/?page_id=144527

I'm not sure your method of using angle aluminum on the lug nut covers is accurate. Those covers just push on and are not the same from one to the next. If it was off as much as your picture shows you would have severe tire wear on the edge. Do not remove the drag link! If you change the drag link position your steering box will have a different number of turns from right to left lock. To straighten your steering wheel, first aim the tires straight forward. Then remove the rubber cover over the lower steering shaft where it goes through the floor. There is a pinch bolt you remove and then pull upward on the shaft off the splines and reposition it onto the splines with the steering wheel clocked correctly. Some of the coaches have a slightly different setup where the sterring wheel shaft meets the splines.

The Cayman Owners Manual lists three warning lights: Low air brake pressure ABS Warning light Jacks down warning light It also says you have a low coolant light and a Check Trans light.

One of the guys (loranimal) on IRV2 rebuilt his Aqua Hot boiler. He posted several pictures. https://www.irv2.com/forums/f115/aquahot-in-pieces-436421.html#post4697140 Also, 97Pariot posted some pictures of his Aqua Hot rebuild on page 3 above. My Aqua Hot was leaking, but I chose to replace the boiler with the new style.

They are groups of air solenoids (6 packs). The rear set is usually in a difficult position above the drive shaft. The coach needs to be up in the air, but you also need to be able to release the air pressure to work on them. Two methods of getting it up in the air. The first is to build some ramps out of stair stepped 2x10" boards screwed together. The second is to cut some very strong steel cylinders or square tubes cut to fit between the frame and the suspension H member. You air up the suspension all the way and then insert the spacers to keep it raised. The air tubing going into the fittings tends to leak after 10 years or so. Sometimes you can remove the tubing (air pressure must be released) then depress the lock and remove the tubing. Cut 1/4" off the end and reinsert it with some WD40 and stop the leak. Other times you need to replace the fitting. The air solenoid six packs have several orings inside. You need to remove the nut on top and disassemble the solenoids and replace the orings. Mike Canter suggests you use Dupont Viton orings. The internal oring is a -019 size, the large one on the bottom is a -028 and the small one on the bottom is a -015 (HWH suspension). It will help to have a special "pin wrench" tool and cannon plug pliers to get the valves apart. Hope this helps.

What brand and model inverter do you have? If you have a Magnum inverter, call Magnum Tech support. From memory, the Magnum inverter AGM 2 charge profile can work with lithium batteries with some adjustments. 800-553-6418 You can also check with your lithium battery manufacturer. Battleborn has great tech support.

You should also call Northwest RV Supply. They have a good selection of leveling systems. 541 746-9092 https://www.nwrvsupply.com/product-category/leveling-slide-out/

Yes, the big Caterpillar engines are thirsty when paired with an Allison. Try driving 62mph or less and do not use the cruise control. The Energy efficient tires may help a bit. Make sure they are properly inflated.

On most of these coaches with larger engines the original filter is undersized. This only matters under full throttle conditions. Unless you do a lot of full throttle pulls, you might consider using your current filter a while longer. Just make sure it's not getting wet or has excessive dust. I think K&N makes some great products. I have a friend that put over 130k miles on his coach with a K&N filter. But, there are some folks that don't think they filter the fine particles. Best of luck!

Great writeup Matt. Many of us do not have air jacks so we use the air suspension to raise the coach and then block it.

Good information above. One caution. If you have only the single 100W solar panel your house and chassis batteries may or may not be charged. Be prepared to use the Boost switch to start the generator and charge all your batteries. Good luck!

It looks like an AN stainless steel braided hose. How much pressure does it hold? We should be able to figure out the diameter, maybe -4 or -6 hose. Then you can remove the old hose and make up a new one. Ten feet of -6 AN hose: https://www.summitracing.com/parts/sum-230610 -6AN hose end https://www.summitracing.com/parts/sum-220690n

Our 1997 Windsor water heater had both 120V and LP. I'm not sure the switches were next to each other. There is a red light that comes on when it's switched on. The 120V is very slow and takes a few hours to heat up. It also doesn't recover quickly. By this time the original hot water heater may have been replaced.

Air Suspension Leaks A large percentage of the time (maybe 90%+) the leaks are in the air solenoid valves, or "6 packs". They need new o-rings installed both inside the solenoid and also where the airlines insert into the solenoid. You need to get the coach up in the air because after you locate the leaks you need to bleed the air down to work on the solenoids. If you do not have a lift, build some ramps from 2" X 12" boards stair stepped together. Someone also posted a link to a leak detector spray product on Amazon that is superior at finding leaks. https://www.amazon.com/dp/B001B00LOS...v_ov_lig_dp_it This process takes lots of time and patience and very few shops have either. HWH will work on your system if you are near Iowa or Paul Maddox. A good way to start would be to search this forum and the Roadmaster section on IRV2 and pre-purchase the o-rings needed. Mike Canter suggests you use Dupont Viton orings. The internal oring is a -019 size, the large one on the bottom is a -028 and the small one on the bottom is a -015. Then remove the 6-pack valves in both front and rear and rebuild them. Label all wires and air lines. Or if you can each, rebuild them in place one at a time. It will help to have a special "pin wrench" tool and cannon plug pliers to get the valves apart. Here are some links to get you started: Air leak in chassis leveling system You Tube video: Air leak in chassis leveling system Hope this helps.

Good job tracking it down. I'm glad you found it.

Sounds like a tough job. Maybe you could post a few pictures?

A 2006 Monaco will have an HWH air ride system and a 2007 will have a Valid air ride system.

I would start by checking the battery ground cable in the basement next to the inverter. While in there, also check the main positive battery cables. Next check the ground cable from the house batteries to the frame back by the battery compartment. Also check the battery disconnect switch cables on the backside of the battery compartment. Hope you find it!

Unlike Bilstein shocks, the Koni FSD shocks are not gas charged. With a pit, you should be able to install them without raising the chassis or removing the tire/wheel. Koni shocks are roughly twice the price of Bilstein, but I think they soften the ride on the front axle. However, the unsprung weight is so large on the rear axle almost any shock will do. Also, remember Monaco uses 4 shocks per axle.

Most of our Monaco dash gauges use a Monaco installed oil pressure sending unit. It's a dual output VDO part number 360 023. One output is for the idiot light and the other is for the gauge. You might try reversing the wires or installing a new sending unit. The sending unit is on the passenger side down near the starter. I accessed it through the rear bedroom access hatch.

I have not measured the hydraulic fluid temperature, but I know it runs fairly hot. It has to power the two large engine cooling fans. I had to rebuild the hydraulic pump and reseal the pump to PTO gasket. I also had a leak in the PTO lube hose from the transmission. The total hydraulic fluid capacity is 50-55 quarts. Also, there should be a hydraulic fluid cooler in the radiator stack.

On our 1997 Windsor it was on the top of the passenger side frame rail adjacent to the transmission. For access, I had to open the hatch in the rear bedroom. Hope you get it working as I don't think these are available anymore.
