Now that I got ur attention..... :BWas in the shop today and the rubber/synthetic sticky tape they put around house windows these days got me thinking. Why not do that on RV's? Wrap the window cutout with Eternabond tape, maybe the 2" stuff, inside the cutout frame and out over the outside. Just enough that it doesn't peek out from beneath the window frame. Then butyl on top to bed the window. Just throwing it out there as a random brain flart. No idea if it's been done before. Just thought it be a good belt and suspenders way to keep water from creeping between the exterior sheathing and the inside of the wall/insulation/frame. Hardhat and oven mitts at the ready!...... Gentle, boys, gentle!

It sounds like it can't hurt anything and might help if you are having water intrusion in that location. When I added an outside vent for the M/W to my trailer I did basically the same thing but used aluminium foil tape instead of Eternabond. If I had thought about the Eternabond I probably would have gone that route.

Should look great with all those 2" wide band aid strips all over the trailer :R. However if resale/looks isn't a issue and the unit will be like a hunters cabin in the woods then looks should be fine.

Would the (minimal) thickness of the Eternabond interfere with the window seating properly on the butyl tape? I'm thinking it could leave a small gap between the window and the side of the RV.Maybe it would be better to just use the tape they use on houses?

It's extremely thin and would make the opening basically waterproof. You would just have to be careful installing the window to avoid tearing the tape.Larry
