Should Butyl Tape Or A Sealant Be Used When Installing Outlet On RV With Aluminum Siding?

Question

Question:

Not a lot of videos on installing the outlet on a rv with aluminum siding, will the included gasket prevent any gaps? Or should I use caulk or some butyl tape?

Hello Jay, thanks for reaching out. Yes, you would want to use butyl tape or a non-sag sealant for that. The gasket by itself would not be enough to fully weatherproof the hole. Maybe we will try to get a video of that next time we see an aluminum trailer here at our shop for electrical work.

Steve, a good rule of thumb is that tongue weight should usually fall between 10–15% of the trailer’s total loaded weight. The challenge, especially with multiple trailers, is knowing where you actually land once cargo is added. That’s where a TW…

Hey Jim, the Replacement Marker Light and Bracket for Furrion Vision S RV Camera System #FR66PR that you referenced actually fits both sides of the trailer so it would be the part you are looking for. Did yours end up broken?
