RV Electrical Problems: 12V & 120V Troubleshooting Guide 2024

Around $500 in parts later — replaced the main breaker, cleaned all connections, checked the transfer switch — my 2007 Holiday Rambler Admiral SE still won't recognize shore power.

I'm pretty sure 110V is making it to the rig since I can measure it, but somewhere between the plug and my appliances, something's not happy. Energy management panel is dark too. What's the logical troubleshooting order here? I keep hearing about transfer switches and breaker panels but honestly don't know where to start without making things worse! …more

No 12 Volt Power in RV: Complete Troubleshooting Guide

Turned the key and nothing works on 12 volt — no lights, no water pump, no slides. Batteries show 12.6 volts on the multimeter so they're fully charged. House batteries seem fine but zero power is getting to any of the 12V circuits inside the coach. …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

Ford F53 Chassis Firewall Wiring: Finding Brake LED Through-Holes

Opened up my 2022 Holiday Rambler 36DB for spring prep and once again I'm staring at my 2021 Ford F53 chassis firewall wondering where those brake LED through-holes are hiding. I need to run the brake indicator LED wire from my toad to the dashboard inside the motorhome, but I'm having trouble locating the best firewall penetration point.

Rather than drilling a new hole through the firewall (which I'd prefer to avoid for obvious reasons), I'm hoping to find an existing through-hole or grommet that I can utilize. I've heard that Ford F53 chassis typically have several factory access points, but I'm not sure exactly where to look or which ones would be most suitable for this type of low-voltage wiring installation.

Can anyone provide specific guidance on where to find existing firewall through-holes on the F53 chassis that would work well for routing brake indicator wiring? I want to make sure I'm using an appropriate location that won't interfere with existing systems and will provide a clean, professional installation. …more

RV Alternator to Lithium Battery Charging: Complete DC-DC Wiring Guide for Safe Installation

Last week I picked up my 2007 Holiday Rambler and discovered the previous owner left the alternator-to-battery charging system a dangerous wiring disaster that could destroy my new lithium batteries.

I'm upgrading from four 6V lead-acid house batteries to lithium, and I keep reading conflicting advice about alternator charging. Some people say "just connect it directly," others are warning about alternator damage and proper current limiting. I'm planning to add a DC-to-DC charger eventually, but I'm confused about whether I can safely use the alternator to charge lithium batteries in the meantime.

What's the right way to handle alternator charging with lithium batteries? Should I disconnect the alternator feed completely until I get a proper charging system, or is there a safe way to make this work without turning my alternator into an expensive paperweight? …more

Southwire EMS Built-in vs External Surge Protector: Do You Need Both?

Opened my 2022 Holiday Rambler 38N DP and discovered it's eating through surge protectors way faster than normal, despite having the built-in Southwire system. Dealer says I might not need an external surge protector like a Watchdog since it's already built in.

Does a built-in Southwire surge guard provide the same protection as a standalone EMS unit? Should I still install an external surge protector or is the built-in system sufficient? Want to make sure I have proper protection without buying unnecessary equipment. …more

5000 lb RV Hitch Rating Explained: Weight Limits, Tongue Weight & Safety Guide

According to my old Class C setup this same hitch rating confusion was easily solved with basic math — but towing a Jeep behind this Class A motorhome has me worried about weight limits and legal liability. After checking the Jeep website, I noticed that most Jeep models weigh over 5100 lbs, which seems to exceed typical 5000 lb hitch ratings. Could this potentially expose RV owners to liability if something goes wrong during towing? I want to understand the weight implications and safety considerations before hooking up a vehicle. Does this mean most Jeep owners towing with a gasser Class A might be inadvertently exceeding safe towing limits? …more

Suburban SF-30 Furnace Replacement: Complete Unit vs Core Guide for RV Owners

Somewhere between our freezing mountain trip last month and now, my 2002 Born Free's SF-30 furnace died completely and I'm torn between replacing the core versus the whole unit. I believe it's a Suburban SF-30 model. I've been doing some research and see there are two options - I can buy a complete furnace replacement or just get a replacement core that supposedly slides into the existing SF-30 housing for about half the price.

I'm honestly not sure which route to go. The cost savings on the core is tempting, but I don't want to make the wrong choice and end up with more problems. As someone who's still learning about RV maintenance, would you recommend getting the complete unit or would the core replacement work just as well? Any guidance would be really appreciated! …more

DPF Failure Code: Repair Cost & DIY Options for RV Diesel

According to my diagnostic scan the DPF failure code shouldn't be appearing since regeneration happened just 500 miles ago on my 2022 Holiday Rambler Cummins B6.7. Local Freightliner service center is quoting $6,400 for complete DPF replacement at 38,000 miles.

Before proceeding with this expensive repair, I need to verify: Is this quote within normal range for dealer pricing? Should my 2022 engine still have emissions warranty coverage that would apply to DPF failure? Are there alternative repair options like professional cleaning that might resolve the issue without full replacement?

Looking for technical guidance on the most cost-effective approach to address this DPF failure code before committing to the quoted repair. …more

Complete Luxury Motorhome Buying Guide for Retirement Full-Time RV Living & Travel

My husband just casually mentioned we're about to drop our entire retirement nest egg on a luxury motorhome when neither of us knows anything about RVs.

I keep hearing different brand names thrown around but honestly have no clue which ones give you the most bang for your buck in that mid-range luxury space. Also wondering if I should buy new or let someone else take the depreciation hit? And what features should I absolutely not compromise on for full-time living?

RV AC Unit Failed After 3 Years - Warranty Claims & Repair Guide

Got a dead front AC unit on my buddy's 2022 Holiday Rambler Endeavor at 2 AM — need this figured out before we hit the road tomorrow morning. We're talking a rig that's not even 3 years old yet! He's got two other roof units still working fine, but this one just gave up.

Is this typical for RV air conditioners? Seems crazy short for something that expensive. Should he be looking at warranty coverage or is he stuck buying a new unit? Any advice on how to handle this with the manufacturer or dealer would be awesome! …more

Ford F53 Motorhome PCM Failure: Complete Diagnosis and Repair Guide

Replaced the PCM on my 1999 Holiday Rambler Ford F53 chassis but still getting complete power loss with coil malfunction codes hitting an entire engine bank. That seems weird, right? Like what are the odds ALL the coils on one side would go bad at once?

I finally wrestled the PCM out (what a pain!) and found some discoloration on one side of the circuit board. Been reading online and seeing mixed info - some say it's the ignition system, others pointing to PCM failure. Really hoping it's not the PCM since those aren't cheap, but the whole bank thing has me wondering. Is this actually pointing to the computer being fried rather than ignition problems? …more

2023 Holiday Rambler Nautica Problems - What To Do Next

I woke up to an $8,000 quote to replace my completely failed Aqua Hot system in my 2023 Holiday Rambler Nautica and wondering if there's any way around this nightmare.

We've only taken four short trips and each one ended with major problems. The local dealer has tried their best but even they seem stumped - the Aqua Hot company now wants $500+ just to look at it again after multiple failed repair attempts. With only 4,000 miles on this RV, I'm facing thousands in out-of-pocket costs for what should be covered issues.

I feel like I've been patient and worked through proper channels, but this RV clearly has serious manufacturing problems. What are my next steps? Are there legal protections for situations like this where an RV is essentially unusable due to repeated defects? I need to know what options I have beyond just accepting these endless repair bills. …more

Holiday Rambler Windshield Wipers Not Working: Fuse & Relay Troubleshooting Guide

Wondering why my 2019 Holiday Rambler Vacationer 36F windshield wipers went completely dead yesterday and now won't budge at all? System shows no power to wipers - no movement, no motor sound, no response from switch positions.

Initial diagnosis indicates potential fuse or relay failure. Located under-dash fuse panel and identified wiper-related fuses and relays, but suspect there may be additional fuse locations in the electrical system that require inspection.

Require confirmation of all fuse box locations for wiper circuit on Ford chassis Holiday Rambler, specifically engine compartment power distribution box accessibility and proper relay testing methodology for systematic troubleshooting approach. …more
