Standing in my driveway planning to tackle these serious handling issues with my new Michelin Agilis HD Z 245/70R19.5 tires on my 2018 Winnebago Vista LX 27N this Saturday — what should I check first? The RV now has 25k miles, and since switching from Goodyear tires, I'm experiencing terrible tail wag - especially when towing my 2024 Toyota Tacoma and in windy conditions.

I've tried multiple tire pressures (82 psi from door sticker, 110 psi from installer, up to 100 psi) but nothing resolves the side-to-side movement. I have several stability modifications installed (Rear Trac Bar, Aux Roadmaster Rear Swaybar, Front Roadmaster Swaybar, Koni FSD shocks), which previously helped with handling.

The movement feels like the towed truck is actually pushing the RV's rear side-to-side, making driving extremely uncomfortable. I'm within Michelin's 60-day/2500-mile buy-back period and want to understand why these tires are performing so differently from my previous set.

Could experienced RV owners help me diagnose what might be causing these handling problems? …more

Staring at my Atwood AFMD35 manual that claims it should stay running once lit, but mine keeps shutting off every few minutes like it's playing peek-a-boo. It fires up beautifully for about 5-10 seconds, gets my hopes up that I won't freeze tonight, then promptly shuts off like it's having second thoughts about this whole "heating the RV" thing.

I've ruled out the sail switch and high temp limit since it actually lights (small victories in RV life, right?). I'm pretty sure the flame sensor is the culprit here, but I've never cleaned one before. How do I clean this mysterious little part, and what's the best way to access it on this model? Because apparently my furnace thinks playing hard-to-get is charming! …more

The YouTube tutorials I followed to fix my Dometic DFMD35111 furnace that runs 10 seconds then dies actually made it worse—now it won't even start! Every time I try to run it, the same thing happens - it fires up, runs for exactly 10 seconds, then just shuts off completely. This has been going on for weeks now and I'm getting desperate since the weather is getting colder.

I've been trying to troubleshoot this myself but honestly don't know where to start. I can hear the blower running and the unit seems to ignite initially, but then it just dies. Is this a common problem with these Dometic units? I'm really hoping this is something I can fix myself rather than having to call out an expensive repair tech.

What are the most likely culprits when a furnace runs for just 10 seconds then shuts down? I need to know what components to check first before I start taking things apart. …more

Since I'm planning to swap out my RV tires this Saturday — need to confirm these Sailun TerraMax HLT-C 225/75R16C E/10PLY tires are compatible with my Class C motorhome. I've been looking at the Sailun TerraMax HLT-C 225/75R16C E/10PLY tires since they seem like a good value, but I'm not sure if they're appropriate for a motorhome versus a trailer.

I know load ratings are important, but I'm honestly not entirely sure how to figure out if these tires would work safely on my rig. Should I be looking at my door placard or getting the actual weight measured? Any guidance would be really helpful since I don't want to make a costly mistake with something as important as tires. …more

Our RV's propane furnace was clicking but wouldn't light, so I followed three YouTube tutorials and now it won't even click anymore! When I flip it on, I hear it clicking away like it's trying to ignite, but no flames ever show up. The clicking goes on for a bit then just stops, and I'm left shivering in my rig.

I've got propane in the tanks and other appliances work fine, so I don't think it's a supply issue. But maybe I'm wrong? Could this be the igniter going bad, or is there something else I should check first before calling a repair shop? …more

Pulled into camp last night and there's this sharp clicking sound followed by dead silence when my Suburban SF-42Q furnace burner dies after 5-10 minutes. The system attempts to re-ignite several times before giving up and shutting down completely. Cycling power restarts the unit, but the same pattern repeats.

I've verified the sail switch operates correctly and the thermal limit switch shows continuity when cold. The unit starts immediately and heats effectively during those initial minutes before failure. What are the most likely causes for this specific shutdown pattern, and what diagnostic steps should I prioritize to identify whether this is an overheating issue, fuel delivery problem, or control board failure? …more

Staring at my 2022 Thor Quantum SE28 furnace after following three YouTube tutorials that somehow made it worse — now it won't ignite despite the blower running perfectly. The unit is getting power and the blower motor kicks on when I call for heat, but I'm not getting any ignition at all - no flame, no heat output. I can hear the blower running strong, so it's definitely getting electrical power, but something in the ignition sequence isn't working.

I've got plenty of propane (3/4 tank) and my stove works fine, so I know gas is flowing to the RV. This is actually the first time I've tried to fire up the furnace this season after it sat unused all summer. The outside vents look clean and I don't see any obvious obstructions, but I'm wondering if there are specific components in the ignition system I should be checking.

What are the most common failure points when you have blower operation but no ignition? I'd like to work through the troubleshooting systematically rather than just throwing parts at it. Are there particular components like switches or igniters that typically cause this symptom? …more

Already spent my RV repair budget this month — is there a way to fix my furnace that just clicks instead of igniting for under $50? The thing keeps making clicking sounds like it's auditioning for a marching band, but refuses to actually ignite and warm up our rolling icebox.

I'm hearing all this clicking and anticipation, like it's really trying its best, but then... nothing. Just cold air and the sound of my dreams of cozy RV evenings slowly dying. Is this a sail switch throwing a tantrum? Bad igniter having an identity crisis? I need some troubleshooting guidance before I resort to wearing all my clothes at once like some kind of mobile marshmallow! …more

Looked everywhere for answers but my 2019 Forest River with an Airxcel furnace won't kick on when I switch the thermostat to heat mode. When I turn the thermostat to heat mode and adjust the temperature setting, absolutely nothing happens - no sounds, no fan activation, no ignition attempts, nothing at all. The unit was working perfectly fine last month during our camping trip, but now it's completely dead when I try to activate it through the thermostat.

I've tried adjusting the temperature settings both higher and lower, checked that the thermostat is properly set to heat mode rather than cool or off, and even tried turning the system off and back on again. The thermostat display appears to be functioning normally and shows the temperature settings I'm selecting, but the furnace itself shows no signs of life whatsoever. I'm wondering if this could be an electrical issue, a propane supply problem, or something with the connections between the thermostat and the furnace unit itself. …more

My Dometic DFMD35111 furnace does the same infuriating thing every fall — lights perfectly on startup then immediately dies out. The flame lights up no problem, but then it just dies out randomly - sometimes after like 3 seconds, other times it'll run for several minutes before cutting out. It's totally unpredictable.

I've already cleaned out some bugs from the burner area and messed with the sail switch, but it's still doing this intermittent thing. The flame sensor looks pretty gunky though. Could that cause these random flame failures? And what else should I be checking when the burn time is all over the place like this? …more

Around two days before our two-week camping trip, I discovered my Suburban SH-42 propane heater's new thermostat wiring might be completely wrong. The unit was experiencing starting issues prior to the thermostat replacement, and I want to ensure proper circuit continuity.

What is the correct thermostat wiring configuration for the SH-42, and what is the proper procedure to test the thermostat circuit to confirm the connections are functioning correctly? I need to determine if the issue is with the wiring connections or potentially the new thermostat itself. …more
