During my morning drive, that sharp, persistent beeping sound erupts from my 2022 Ford E-450 motorhome dashboard as the "Tire Pressure Sensor Fault" message flashes relentlessly. Because nothing says "relaxing RV vacation" like mysterious warning lights, am I right?

The intermittent fault seems to be coming from the rear tires mostly, and of course it always happens at the most inconvenient times - like when I'm trying to convince my spouse that this whole RV lifestyle was a brilliant idea. I'm wondering if this is just a typical TPMS sensor going bad or if there's some sort of relearn procedure I need to do?

Since this beast is still under warranty, I'm hoping there's a straightforward fix that doesn't involve me pretending to understand tire sensor technology. Anyone know what the usual culprit is for these TPMS faults on the E-450 chassis? …more

Nobody wants to deal with the same front marker light issues on their 2013 Forest River Georgetown 377XL's Ford F53 chassis every single camping season.

The lights work sometimes but not others, and I can't figure out the pattern. I've already checked fuses and replaced the bulbs, but I'm hesitant to start pulling apart wiring without knowing what I'm doing. I keep reading about electrical problems getting worse if you don't fix them right, and I really don't want to create a bigger issue.

What are the most likely causes for intermittent marker light failures on F53 chassis? I'm hoping there's a systematic way to troubleshoot this without risking damage to the electrical system. …more

Three days before our family reunion road trip and my 2012 Thor Daybreak's battery keeps dying overnight with these crazy electrical issues. Battery keeps going dead and I'm pulling about half an amp even when everything should be off. Here's the weird part - when I mess with the instrument panel dimmer switch, the parasitic draw actually changes! Goes from like .12 to .45 amps depending on the setting.

Plus a bunch of my lights decided to quit working all at once - tail lights, running lights, license plate light, the works. But other stuff like headlights and turn signals are fine. The whole thing seems connected somehow since it all happened around the same time.

I can stop the drain by pulling a couple specific fuses (the instrument cluster one and the body builder 12V feed), but obviously that's not a real fix. Ford dealer has had it for weeks and they're stumped. Anyone dealt with this kind of multiple circuit weirdness on a Daybreak before? …more

Noticed my 2025 Jayco Precept 29V windshield wiper motor completely died after I followed a YouTube repair tutorial that somehow made everything worse. The system appears to be integrated with the Ford chassis electrical components, but I need to systematically troubleshoot the root cause before pursuing warranty repairs.

What are the primary failure points in the Jayco Precept wiper system, and what diagnostic sequence should I follow? I need to verify whether this is a fuse issue, switch malfunction, motor failure, or mechanical linkage problem. The symptoms suggest electrical failure, but I want to eliminate all possibilities methodically.

Specifically looking for guidance on the Ford chassis integration and most common failure modes for this model's wiper system. …more
