Ford E450 Inertia Switch Location Guide - Find Your RV's Fuel Cutoff Reset Point

Every Ford E450 I've worked on had the inertia switch behind the driver's panel — but my 2011 Freedom Elite 32r has it hidden somewhere completely different. The engine is experiencing what appears to be fuel delivery issues after a minor fender bender, and I suspect the inertia switch may have been triggered and needs to be reset.

I've already done extensive searching in the typical locations - removed both driver and passenger side kick panels completely, pulled out the glove box, and even partially disassembled sections of the dashboard. Despite checking all these common spots where Ford usually places these switches, I'm coming up empty-handed.

Could the switch be integrated into another component on this particular year and model? Are there any alternative locations specific to the E450 chassis or Freedom Elite configuration that I should be checking? I'm also wondering if some models of this year might not have a traditional standalone inertia switch at all. …more

Georgetown GT7 Lithium Battery Conversion: Complete RV Installation Guide

Turned the keys on my 2023 Georgetown GT7 and discovered the previous owner left the electrical system in complete shambles, now facing this intimidating lithium conversion nightmare. I know I need LiFePO4 batteries, but every forum post I read mentions different components and I'm getting conflicting information.

I really want to make this upgrade work - the lead acid batteries are killing me with their weight and charging limitations. What specific components do I need beyond the actual lithium batteries? I'm especially confused about whether my converter will work and if I need additional charging equipment for the alternator. Please tell me my 2023 model year gives me some advantage here! …more

RV AC Making Loud Humming Noise? Fix Compressor Not Starting

Somewhere above my head, there's this loud, relentless humming grinding through the RV whenever I flip on the rooftop AC — compressor won't start but the fan spins fine.

I've been dealing with this for days now and it's driving me crazy - especially with the heat we've been having! The humming is so loud that I'm worried something might be seriously damaged. I really hope this is something I can fix myself rather than having to call out a repair tech. What could be causing a compressor to hum loudly but not start up? …more

RV Inverter Guide: Modified vs Pure Sine Wave - Safe Power

My multimeter's out and I'm ready to tackle this RV electrical mess myself — pretty sure the inverter's the culprit but need to know where to start. I have a 2000 Winnebago Ultimate Advantage with four deep cycle house batteries and recently installed a Xantrex 758 inverter to replace my old Freedom 15 unit. The first time I tried using the inverter power while unplugged from shore power, something very strange happened - a hair dryer in the bathroom started running by itself and wouldn't shut off when I tried the switch. I had to unplug it, and the handle was warm. The hair dryer appears to be ruined now.

When I bought the Xantrex 758, I paid around $725 for what I thought was a good unit, but I'm now learning there's a difference between modified sine wave and pure sine wave inverters. I wasn't aware of this distinction when I made the purchase, and it turns out the 758 is a modified sine wave unit. I've since heard that modern electronics, especially things like residential refrigerators, computers, and sensitive electronic components, can be damaged by modified sine wave power.

I'm really concerned about potentially damaging my new residential refrigerator, stereo system, and computer equipment. Should I be worried about using this modified sine wave inverter with modern RV electronics? Is the hair dryer incident a sign that I need to upgrade to a pure sine wave unit, or are there other factors that could have caused this problem? I'm trying to understand if my current setup is putting my expensive electronics at risk. …more

RV Storage on Gravel: Preventing Weed and Moisture Issues

Nobody warned me that buying a house with RV storage meant inheriting the previous owner's 13-year-old weedy, muddy gravel disaster. While considering this location's storage options, I want to mitigate potential issues with weed growth and moisture retention under the RV.

I'm seeking advice on effective strategies for storing on a gravel surface that shows significant weed penetration and moisture retention. Initial ideas include pre-treatment herbicide application and installing a protective barrier, but I want input from experienced RV owners.

My primary concerns are preventing undercarriage damage and managing moisture/vegetation growth. I plan to spray weed killer beforehand and potentially lay down a weed barrier, pending facility approval. What techniques or materials do you recommend to protect my RV during storage? …more

Atwood GC10A-4E Replacement: Best Tankless RV Heaters

Halfway through draining my Atwood GC10A-4E's supposed 10-gallon capacity, the water's already running cold but my gauge shows I've only pulled maybe 6 gallons. Are there any dual-fuel tankless units that would work as a replacement? I know there's no plug-and-play option, but what are the best tankless water heaters that offer both gas and electric operation for RVs? …more

RV Engine Stalling & Transmission Issues - Diagnosis Help

Replaced multiple parts but I'm still standing in the auto parts store aisle staring at diagnostic tools with no clue which one I actually need for my RV's stalling and transmission issues. When I'm cruising and let off the gas, sometimes the RPMs drop like a rock, other times they just hang there until I slow down more. That's weird enough, but here's the real kicker - every now and then the whole engine just dies on me when I'm rolling up to a stop sign or red light. Maybe happens twice in 600 miles or so, so it's not constant but definitely not normal either.

I'm wondering if these two issues are connected somehow? Like could whatever's causing the stalling also be messing with how the transmission acts when I let off the throttle? Really hoping someone has seen this combo before because I'm in Germany and finding RV-specific help is tough.

I'm looking for any insights from folks who might know what could cause this - hoping to get to the bottom of this before it becomes a bigger problem! …more

Protect Your RV Alternator When Charging Lithium

Tried everything my neighbor did to charge his LiFePO4 batteries but mine keeps frying the alternator while his works flawlessly — what's different? I want to install a temperature sensing device that can interrupt charging by opening the solenoid between chassis and house charging systems if the alternator gets too hot. I'm looking to spec out components and understand the installation process, and I'm open to hearing why this might not be a good approach. My goal is preventing alternator overheating when these lithium batteries draw high current compared to my old flooded or AGM batteries. I'm looking for technical feedback and am totally open to critique. …more

RV Battery Draining Overnight? Find & Fix Parasitic Drain

The day after I installed that new solar charge controller last month, my RV batteries started mysteriously draining from fully charged to completely dead overnight. I've already confirmed that all visible lights, fans, and appliances are turned off, and I've switched off the main interior power, but something is still drawing power continuously. I understand this is likely a parasitic drain where some component or circuit is staying energized when it shouldn't be, but I'm not sure how to systematically track down which specific circuit is causing the problem. I have a basic multimeter but I'm not entirely sure about the proper methodology for testing each circuit individually to isolate where exactly the power draw is coming from. What's the step-by-step process for using a multimeter to methodically work through the electrical system, starting from the main disconnect and testing individual fuses or circuits until I can pinpoint the exact source of this parasitic drain? …more

How to Fix a Squeaking Dometic Fan-Tastic Roof Fan in Your RV

Looked up at my Dometic Fan-Tastic roof fan squeaking loudly above my kids' beds—is this dangerous or could something actually break and fall on them?

Xantrex Freedom X 1200 Inverter Low Battery Warning: Critical 11.2V Fix Guide

Walked into my new RV and discovered the previous owner left the Xantrex Freedom X 1200 inverter constantly throwing critical 11.2V low battery warnings. My Xantrex Freedom X 1200 inverter is displaying warning indicators on the panel, and I'm seeing some concerning voltage readings that have me worried about potential damage to my electrical system.

Here's the complete situation: My house battery is reading 11.2 volts, while the chassis battery shows 13.1 volts. The inverter panel is lit up with what I assume are low voltage warnings. I've been noticing the interior lights dimming significantly, especially when trying to run any appliances through the inverter. To make matters worse, it's currently overcast and getting dark, so my solar panels aren't generating any meaningful charge to help recover the battery.

I'm particularly concerned because I know lead-acid batteries can be permanently damaged if they're discharged too deeply. The voltage reading of 11.2V seems critically low to me, but I want to understand exactly how urgent this situation is and what my immediate next steps should be. Should I be looking at shore power connection, generator use, or is there something wrong with my charging system that caused this in the first place? I need to know both the immediate fix and what might have caused this failure. …more

RV AC Freezing Up? Fix Ice on Coils in 5 Steps

Turned on my RV's AC as a total newbie and watched it run perfectly for an hour before becoming a frozen disaster that won't cool. I can literally see ice building up on the coils, and then it's game over until everything thaws out.

This has happened a few times now and I'm getting tired of sitting in a hot RV waiting for the thing to defrost. What actually causes AC units to freeze up like this? And more importantly, how do I stop it from happening again? I'm guessing it's something simple I'm missing, but I'd rather fix it right than keep dealing with this cycle. …more

How to Remove Firefly RV Control Panel: Complete DIY Guide

Our 2019 Fleetwood Discovery LXE has a malfunctioning Firefly multiplex control panel that needs to be completely removed. I've been putting this off for months because I keep hearing horror stories about people cracking their panels or damaging the surrounding woodwork during removal.

I need to access the back of the unit for some electrical work, but I'm honestly terrified of breaking something expensive. The panel seems to be mounted flush with no obvious screws or clips visible from the front. I've searched everywhere but can't find a complete walkthrough that covers the preparation, actual removal process, and how to get everything back together properly.

Can someone please provide a detailed DIY guide that covers all the steps? I'm willing to take my time and do this right - I just need to know the proper technique so I don't end up with a broken control panel or damaged wall. …more
