2020 Thor Vegas - roof leak and electrical issues

I picked her up in FL and drove to San Diego - that was fun! - (though I'll be installing a Safe-T-Plus)

But -Significant leak above the shower area - in the skylight. No need to turn on the faucets when it rains!

Only one 110v plug in the whole rig works. Hope these aren't related. Checked/reset breakers and GFI's no luck

Would a roof leak like this already be inviting electrical problems (Is there a sub roof aka interior water problems) or is the water likely confined to the skylight assembly and shower/bath area?

I want to be careful not to invalidate warranty.

Driving back to FL in March for service but hoping for some resolve until then.

Being in Michigan, I would set up an appointment asap with the factory service center just below you in Wakarusa. You're under full warranty. No one knows your coach better than them and it's much closer than a dealer in Florida. They will make repairs and run it through the "rain maker" to test it. I don't know of a dealer anywhere that has that feature.


Possibly a stupid question, but you say only one outlet works on 120V. Was this when plugged into shore power or with generator running also?

The rig is in Solana Beach, CA at the moment. I fly out there on days off and take it to either San Elijo or South Carlsbad campground during my stays. With shore power, generator, or with engine running almost all 120v plugs are inop.

I picked it up at General RV in Dover, FL and am coincidentally headed that way for the Sun-n-fun airshow in April (thus the service appointment there). Planning to head back to Michigan in May so I'll still be under warranty.

It may be an incomplete seal around the skylight. I'm just hesitant to apply my own fixes so assumptions aren't made that I contributed to the initial problem.

We set up a service appointment and asked for a list of issues they need to address. There are many but the a don't want to rant because I really love my new rig.
I want to install AGM batteries and set up solar (plus inverter) but feel like I shouldn't touch anything until I've documented the initial problems (without having touched anything).

Great mod thread btw. I'm planning upon doing a number of them as time allows.

Use whatever you have to to temporarily seal it. Just let Thor know what you're doing so its on record. Open the box for the Transfer Switch and check all the wire connections. This is a common issue with new MH's as well and will prevent incoming power. If you have an inverter, the only switch working may be connected to it. I have one plug in BR that is connected to inverter. I guess it's for an alarm clock...hmmm...an alarm clock in a motorhome makes as much sense as braille on a drive-thru ATM.

On my 24.1:
Just above the toilet on the bottom of the overhead cabinet, is a gfci outlet. You'll might need a flashlight to see the brown outlet on the brown cabinet bottom.
You said you checked but I'm not sure where you checked. This one is hard to see and hard to see and you've pretty much gotta be sitting on the can to operate the gfci.

Unless you installed one, I'm fairly certain a 24.1 doesn't come with an inverter.( I always found this an odd place to cut costs. $200 bucks more onto the bottom line. I'd think going to 13,500 from the stock 15,000 would cover costs... And who'd know much about the ac shortage...' Hey! Look! It has an inverter!')


Thor corporate is very forgiving.
You've documented the problem. They'll understand a fix being made.
Buy some tape and fix it... If you're sure that's where the leak is.
It could be running from even a front marker light and the skylight is the best exit route.

Will apply the seal. I also made some video documentation of the leak.

I'll have a look at the Transfer Switch - under the right rear bed?

I basically make a list of things to bring from the Michigan house (from tools to supplies) and work on it while I'm in Southern California.

The plug in your BR is to connect tanning lamps above the bed. That way you come home with a tan no matter where you went!

I'll have a look for the GFI - I reset all that were noticeably visible but didn't see that one.

Should I have any concern regarding mold or residual moisture having had internal leaking at such an early stage in the game?

Haven't installed an inverter but I'm planning to (along with solar). The campground charges an extra $25/day for hookup spots. I'll be staying in my Vegas close to 20 days next month. The savings alone will go a long way toward covering the cost of the upgrade.

Mold is a long term thing.
You'll be fine.
At worst some seperation of the cheap plywood, but I sure wouldn't worry.

Then that's the hidden gfci culprit, or it has been on every 24.1 I've helped with your problem.
We've had ours just a year last halloween and only a toy hauler ten years ago for a short time. Imagine how good you'll be at this in a year....

Thanks for the compliment on the mods.
I'm hoping they have value to someone.
If you can think of any improvements on any of them, I post them only so I can get a group grope on improving my base.
Don't hesitate to tell us how you modded a mod.

120 VAC outlets don't work off the Engine running, only the generator and Shore Power.

So which outlet DOES work?

The aft ceiling outlet above the couch in the living room.

In the ceiling? Do you mean under the cupboard? I don't see any outlets in the ceiling.

I also don't have one in the ceiling, but I know that under cabinet/over the couch too well.
I had a short in the wiring to that outlet which blew shore power only, never a house breaker, never gfci. If it's wired hot like the op says, it would sure explain how that happened to me. When we put the slide out, shore would pop.

Bear in mind my 24.1 is a 2018. Though I think the differences are cosmetic and the Bluetooth system for control.

Sorry, the rig is in California at the moment so I'm going from memory. Yes, under the cupboard.

That's the only one that works.

The hatch above the cockpit of the Boeing 787 I fly leaks too and that thing runs $220,000,000. Must just be my fate to get wet!
