Finding my leak

[Bowhunter61]

I had posted about a leak I had back in 2016, took it to a dealer and they supposedly used a SealTech and found the issue. Well only a couple months later when I brought it down to my land in TN, I found the leak was still there. I have been keeping it under cover the last 4 years in a pole building at our TN property so I haven't worried about it until now. Our house is built now and we are ready to start using it again. So I took it to a dealer here and they again supposedly fixed it, said it was the corner trim on the back edge of the garage. Left it out in the rain yesterday and leak is still there.
Here is the original thread

it's a fuision TH, So I wanted to throw my plan out here and see if people could give me some recommendations.

Plan: I am going to tackle finding this myself. I figure I can rig up my own "SealTech" type of system. First I am going to seal the garage area because that is where the leak seems to be coming from. I have a big slider door that isolates the garage from the rest of the unit. I am going to use an electric leaf blower with a dry vent tube hooked to it and run it into the side vent of the garage (vent that can be opened to let our fumes). I will tape the seams on the ramp door. Then use a mix 1-3 soap to water to spray on all the windows and corners then up to the roof.

Anything else I would need to be aware of?

Thanks

Best of luck finding that leak. It's not always anywhere close to where it shows up on the inside.

Getting enough pressure inside the rig to find that leak is unlikely, but ya got nothing to lose for trying. Again, best of luck. You will be amazed to see how many air vents you have that you never knew existed.
