Last week my 2006 Monaco Diplomat's rear air bags started refusing to dump all the way down when I hit the air dump before leveling. The front dumps fine, but the back stays partially inflated.

I'm still pretty new to RV maintenance and not sure where to start troubleshooting this. Should I be hearing air escaping when I activate the dump? What are the most common causes when rear air bags won't dump completely? Any guidance on what to check would be really appreciated! …more

Halfway through my first RV ownership experience, Camping World dropped the bomb that my Thor Ace 29.2's rear cap has delamination and I'm completely clueless. The back doesn't feel like typical fiberglass - none of the other sides move like this. Is this movement normal for this RV model, or is it a sign of serious damage? …more

About to drop $2,800 on my Cummins ISL throwing code 1896 for EGR valve controller out of calibration and wondering if I can tackle this myself. Planning to pull and clean the EGR valve controller to see if that clears it up.

Do I need to order replacement gaskets before I start this job? Want to make sure I have everything on hand before I tear into it. …more

Opened up my RV window seals yesterday thinking I fixed the leak, but water's still dripping through during today's downpour — what did I miss? The rubber seals around the frames are obviously shot, all cracked and dried out looking.

I'm torn between two approaches here: should I take the time to completely remove the old seals and put in new butyl tape/rubber sealing, or can I just run some caulk over the existing stuff and call it good? Looking for the best long-term fix that'll actually keep me dry! …more

Halfway through every tool in my garage — flathead screwdriver, wheel puller, rubber mallet — and these stubborn RV wheel simulators still won't come off for tire pressure checks. flat on my back in a truck stop parking lot, staring at what I think is a wheel simulator that's laughing at me. I need to check my rear tire pressure, but this thing is stuck tighter than my budget after buying this money pit on wheels.

I can see two nuts at the 9 and 3 o'clock positions that look like they've seen some action (one's even got a split down the side - yay, previous owner "repairs"). They budge just slightly when I try to loosen them, but won't come off even with my impact wrench. My brilliant brain is now wondering: should I just pry this simulator off, or do I really need to get those stubborn nuts loose first? Because knowing my luck with RV repairs, I'm about to turn a simple tire pressure check into a $500 mistake! …more

Walked out to my 2018 Newmar Dutch Star this morning and the air suspension is taking 4-5 minutes to reach ride height on startup. Just wondering if that's normal or if I've got something going on that needs attention?

Not sure if this is just how these systems work or if I should be looking at the compressor or checking for leaks somewhere. What's the typical time frame for air suspension to get up to proper height? …more

Somewhere between my third passenger-side drop of 1.5 inches this season on my 2021 Jayco Alante, I'm officially done with the guessing games on this lean. I've checked and it's not because of full tanks or uneven loading. When I had it looked at, they said the frame and suspension are square and level, so that's not the problem.

I'm thinking it might be something with the body mounts? Could this be loose bolts or worn rubber parts? I've heard about body shims but not sure if that's the right fix. Since it's still pretty new, would this be something covered under warranty? Any guidance would be really helpful - I want to make sure I'm approaching this the right way. …more
