RV DC Electrical System: Expert Guide to 12 Volt Systems

Opened my RV this morning to find the 12V system going haywire — lights dimming randomly, fans slowing down, and the inverter shutting off despite full batteries.

Specifically, I need to understand the fundamentals of RV batteries - different types, proper sizing, charging requirements, and maintenance. I'm also confused about DC wiring best practices, what gauge wire to use for different applications, how to properly route and protect circuits, and where fuses and breakers should go. Voltage monitoring is another area where I'm lost - I see all these battery monitors and don't know what I actually need or how to interpret the readings.

I'm also planning some system upgrades down the road like adding solar or upgrading to lithium batteries, so I'd love to understand how all these components work together and what I need to consider for future modifications. Is there a comprehensive resource that covers all aspects of RV DC electrical systems from batteries and wiring through monitoring and upgrades? …more

Fleetwood Excursion Tire Upgrade Guide: 255 to 275 Width Conversion

After upgrading my 2015 Fleetwood Excursion M-35B from 255 to 275 width tires, it started getting sketchy handling on highway turns. The current 255/70R22.5 tires are wearing out and I'd love to go wider with 275/70R22.5 for better stability, but I keep getting conflicting advice from different tire shops.

Some say it's fine, others warn about clearance issues and potential problems. I really need to know what specific measurements I should check before making this change. What wheel width do I need? How do I verify there's enough steering clearance? I don't want to buy expensive tires only to find out they don't fit properly or aren't safe for my RV's load requirements. …more

How to Fix RV Slideout Rubbing Against Exterior Wall - Complete Repair Guide

Finally figured out why my neighbor's slideout glides like butter while mine scrapes horribly against the exterior wall every time — what's their secret? My slideout has started rubbing against the exterior bathroom wall, and the coach is perfectly level.

The main thing I've noticed is that the gap at the bottom of the slide is much smaller now compared to the top - it used to be about 1½-2 inches at the bottom, but now it's barely anything. There's also about a ½ inch difference in height from one end of the slide to the other when I measure from the top.

I've independently jacked up both sides of the slide more than an inch each and checked the gap, but neither showed a difference. When I crawled underneath, I couldn't see where the slide might have moved laterally closer to the wall. The exterior stripes still line up. I also noticed the shower hasn't been used in 6 years or longer (I bought this coach used).

I'm wondering if this could be some kind of drooping issue? I've heard about things like rollers wearing out, but I honestly don't know what to look for or where to start troubleshooting. Should I be checking underneath the RV? Any advice on what might be causing this rubbing and smaller gap would be hugely appreciated! …more

How to Replace Your RV Door Awning Motor Cap: Step-by-Step Guide

I tried getting answers about my RV sideswipe damage but my insurance adjuster says it's totaled, three body shops say fixable, and forums are completely split. The coward took off at the highway exit before I could get his plates. Damage is to the bay doors and right front corner cap area - looks pretty ugly but the RV is still drivable. Police never showed up despite multiple calls over 4 hours of waiting. Already filed with insurance and sent photos, but I'm wondering what I should be looking for beyond the obvious visible damage. This is my first accident in 8 years of RVing and I'm stressed about hidden issues I might miss. Any advice on what to inspect or document before the adjuster comes out? …more

HWH RV Slide Hydraulic Hose Repair: Complete DIY Guide

Replaced my HWH slide's hydraulic hose last month and now it's spraying fluid everywhere again with our three-week cross-country trip starting Friday! My 2007 Monaco Dynasty with HWH hydraulic system decided to throw me a curveball when the bedroom slide hydraulic line (1/4" I.D.) decided to spring a leak. After some detective work (and a lovely puddle of ATF to mark the spot), I traced it back to where a 1" air line to the front caliper had been playing the world's slowest game of 'saw through the hydraulic hose' for who knows how many miles.

I temporarily patched with Gorilla Tape and 1/2" hose clamps, which got the slide almost closed but still creeping. I'm planning to fix this with a compression coupling since that seems like the most straightforward approach for a DIY repair. Two quick questions: Can anyone confirm the 1/4" I.D. hose size for HWH systems? And once I get this coupling installed, will I need to bleed the system, or does it sort itself out? I'm hoping this repair goes smoother than my attempts to explain to my spouse why we're currently camping with a slide that's permanently 'almost' closed! …more

Dometic CF80 Drain Foam Replacement: Complete Step-by-Step Guide

Woke up to check out my new place's Dometic CF80 basement refrigerator/freezer and discovered what looks like deteriorated foam filter stuff in the bottom drain compartment. The foam material shows significant contamination and degradation.

I need to understand the specific function of this foam component within the CF80's drainage system. Is this foam element critical for proper unit operation, and what are the consequences of operating without it? Additionally, what is the recommended replacement schedule for this component, and how do I determine when replacement is necessary versus simple cleaning? …more

Ford F53 Front Wheel Bearing Failure: 2018-2019 Chassis Problems & Solutions for RV Owners

I spent a fortune replacing front wheel bearings on my 2018-2019 Ford F53 motorhome because they keep failing way faster than normal, and apparently other RV owners are getting hammered too. A friend's 2018 F53 chassis just had a complete bearing failure at only 22,000 miles - the wheel was literally at an angle and destroyed the tire too.

This has me worried sick about my own rig. Are there documented issues with premature wheel bearing failures on 2018-2019 F53 chassis? I'm seeing reports of failures happening way too early, and I'm terrified of having a catastrophic failure while driving. What's causing these failures and should I be doing something preventative before I end up stranded on the highway? …more

Ford V10 Lower Radiator Hose Replacement: Complete RV Repair Guide

Standing next to my Ford V10 E350 staring at this lower radiator hose that's clearly shot and needs replacing before my next trip. The complex multi-segment design of the V10's lower hose system has me a bit concerned about the replacement process, especially since I've heard these can be tricky to install properly.

Specifically, I need to understand the complete procedure from start to finish. What's the proper way to drain the coolant system before starting? Are there any special considerations for hose selection or clamp replacement that I should know about? Most importantly, what's the correct bleeding procedure afterward - I've heard air pockets can be a real problem with the V10 cooling system if not done properly.

I'm planning to tackle this myself in my driveway, so I want to be fully prepared with the right steps and any tips that will help ensure the job goes smoothly without any cooling system issues down the road. …more

Aqua Hot Engine Coolant Hose Failure: Emergency Roadside Repair Guide for RVs

Despite what started as a minor Aqua Hot coolant leak in my Western Alpine motorhome last month, the engine coolant hose has now completely blown out three times this week crossing Texas on I-10. Each time it happens, I lose coolant and have to find a repair shop, but the repairs don't seem to be holding up to road conditions and vibration.

The first failure happened about halfway across Texas, got it repaired at a local shop, but it blew again after only 80 miles of driving. Made it to Houston where it failed a third time, and now I'm stuck at Auto Tech Center in Kingwood, TX (owned by Wendel Walden), paying $50 a night for water and electric, plus $225/hour for labor. I'm also facing additional costs of $10 a day to store a box trailer I need to pick up on the south side of Houston.

What are my options for emergency roadside repairs when this type of Aqua Hot coolant hose failure happens? Should I be carrying specific spare parts and tools for this type of repair? Is there a way to temporarily bypass the Aqua Hot system entirely so I can at least get to a proper repair facility without risking further engine damage from coolant loss? …more
