RV Sidewall Blistering & Delamination Repair Guide 2024

According to three different RV shops, fixing my bubbling sidewall delamination will cost thousands, but I'm wondering if tackling this DIY repair myself is actually feasible. My 2004 Itasca Sunova has decided to sprout some lovely blisters on the right sidewall - two beauties that are about 12-14 inches long and 3-4 inches wide, running vertically right behind the awning arm. Perfect timing since we're currently on the road living our best RV life!

I'm pretty sure water snuck in somewhere (probably from the roof rail or that shower skylight we never use), and now my RV looks like it's got chicken pox. Since we can't exactly pull into the nearest RV surgeon's office, I need to know: what can I do right now to stop this from getting worse, and what's involved in actually fixing this mess properly? I'm hoping there's some kind of emergency containment plan that doesn't involve duct tape and prayers! …more

RV Rubber Roof Bubbling? How to Repair EPDM Separation

After 8 years of faithful service, my RV's EPDM rubber roof is starting to bubble with the membrane separating underneath — should I repair or replace? I'm concerned that if I don't address this soon, water could get in and cause major damage.

But I'm also nervous about trying to fix it myself. What if I make it worse by cutting into the roof or using the wrong products? Is this something that can actually be repaired, or am I looking at a full roof replacement? I'd really appreciate some guidance on whether this is a DIY-friendly repair and what the basic process involves. …more

How to Reduce RV Interior Noise: Complete Sound Dampening Guide for Motorhomes

Despite having a 2021 Coachmen Mirada, looking at my sound meter right now and there's 69 decibels of highway noise blasting through the cabin. My target is to achieve approximately 65 decibels for better communication with passengers.

I need a systematic approach to interior noise reduction. What are the most effective sound dampening materials and techniques for motorhomes? Specifically, I'm looking for solutions that address engine noise transmission, road noise, and any rattling components that contribute to the overall sound level.

What realistic noise reduction can I expect from proper sound deadening implementation, and what are the key areas to focus on for maximum impact? …more

Thor Ace Fiberglass Rear Cap: Repair and Maintenance Guide

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

RV Roof Leak Around Air Conditioner: Complete Repair Guide

Around noon Saturday I'm planning to tackle this stubborn RV roof leak by my air conditioner — what tools should I gather beforehand? My rooftop air conditioner is letting water in every time it rains, and when I climbed up there (probably looking like a graceful gazelle), I can see the sealant around the AC unit is definitely cracked and peeling.

I'm standing in the RV section of the hardware store looking at about 47 different tubes of sealant, and I have no idea which one won't turn into another cracked mess in six months. What's the best product to properly reseal around an RV air conditioner? I'd rather not repeat this whole 'indoor rain shower' experience again! …more

How to Fix Cracked Dometic RV AC Covers & Roof Vents: Complete Repair

Already tried following a YouTube tutorial to fix the cracked Dometic air conditioner cover on my 2022 East to West 1900MMK travel trailer but somehow made the crack even worse. What are my repair options - can I fix the crack or should I replace the whole cover?

Also dealing with a broken cap on the roof tank vent. I'm curious about material choices - I've noticed galvanized steel can rust, while PVC seems to degrade in sunlight. What are the pros and cons of different vent cap materials? What's a reasonable price range for replacement?

Looking for practical solutions for both issues. …more

MaxxAir Fan Shuts Off During Shower? Quick Sensor Fix Guide

Our MaxxAir fan keeps shutting off every time someone showers, so we're trying to decide between replacing the rain sensor or just living with it. The rain sense is turned off on the remote, but it still happens. After it closes, the remote won't control it anymore until I manually open the vent with the knob on the unit itself.

Is this a moisture sensor problem or rain sensor malfunction? What's the typical fix for this issue? …more

How to Lift RV Slideout for Floor Repair - Safe Methods

How to Lift RV Slideout for Floor Repair - Safe Methods

Apparently my 2000 Allegro Bus slideout only starts sagging and needing floor repair when it hits 85 degrees outside — works perfectly fine otherwise. We discovered water damage under the slideout and need to replace some plywood subflooring, but there are screws I can only access if I lift the slide somehow.

I'm worried about damaging the slideout mechanism or worse, having it fall and hurt someone. The hydraulic system seems to work fine, but I've heard you shouldn't trust it alone for this kind of work. What's the safest method to lift and support a slideout while doing floor repairs underneath? I want to make sure I'm not making a dangerous mistake here. …more

How to Repair RV Roof Soft Spots: Fix Water-Damaged Wood Step-by-Step Guide

My RV roof has had this squishy soft spot right next to the roof vent ever since we got hammered by that nasty rainstorm last month. When I step on that area, it feels spongy and I can tell there's water damage underneath the rubber membrane.

I'm pretty sure water has been leaking through the vent area and rotting the plywood underneath, which seems to be about a hand-sized area. I want to cut the rubber membrane back, replace the damaged wood, and then reseal it properly.

Should I be worried about the structural integrity? What type of materials should I use for the replacement wood, and how do I properly reseal everything to prevent this from happening again? I'm thinking of folding back the rubber, replacing the damaged section of wood, and then resealing the membrane over the new wood. …more

RV Window Seal Leaking: Complete Repair Guide & Solutions

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

Can You Remove RV Slideout Topper Temporarily? Safe Travel Without Awning

Since that heavy downpour last weekend, my slideout topper mechanism completely failed - something snapped inside the roller tube and now it won't retract at all. I managed to manually wind it up and secure it with zip ties just to get home, but it's clearly done for.

I've got a replacement topper on order, but of course it won't arrive before our next planned outing in two weeks. I'm really hoping we don't have to cancel this trip we've been looking forward to! Can I safely remove the broken topper completely and just operate the slideout normally without it? I assume it should be fine since it's just for keeping debris off the roof, but I want to make absolutely sure there are no safety issues with traveling and using the slideout without the topper installed. Any advice would be hugely appreciated! …more

Coleman Mach AC Leaking Water Inside RV: Complete Troubleshooting Guide to Stop Drips

I'm planning my weekend getaway when I spotted water dripping from my Coleman Mach air conditioner model 49003A879 that definitely wasn't there yesterday. I'm in Myrtle Beach, with super humid conditions (90s with crazy humidity) and getting pea-sized water drops falling from the ceiling vents at maybe 2 drops per minute, which doesn't sound like much but it's making puddles on my floor.

I've been keeping the main ceiling vents mostly closed to push more air to the back of the coach. Climbed up on the roof expecting to find some fancy drain pump or tubing system, but honestly don't see much of anything obvious.

Is this just how these Coleman units work, or am I missing something? Really hoping this isn't a 'deal with it' situation, but wondering if my closed vents are screwing up the airflow or if there's actually a drainage problem I need to fix. …more

Fix Splendide Washer/Dryer Towels Stuck to Drum Issue

Our new-to-us RV came with a Splendide washer/dryer combo that the previous owner left in terrible shape — it turns towels into matted clumps stuck to the drum. This problem occurs regardless of load size variations - both light and heavy loads produce identical results.

The matted towels require manual separation and often necessitate running additional wash and dry cycles, though this remedial approach yields inconsistent results. The towels appear to compress into solid masses that conform to the drum's curvature.

Seeking technical analysis of potential root causes and systematic troubleshooting procedures to eliminate this operational malfunction. What mechanical or procedural factors contribute to this towel matting behavior, and what specific corrective actions should be implemented? …more
