Black vs White
Just went camping at Calico Ghost Town in Barstow, CA with temps up to 105 degrees. The A/C ran all day and only brought the trailer temp down to 81 degrees. While outside I looked up and noticed the...

Good video and I'm gonna check mine. But I'm thinking a silicon caulk where the air leaks between the cold output and hot return will hold up better than tape with adhesive on it. It seems that adhesive glues always let go with heat and any stick on material will suffer the same fate as the adhesive liquifies. One man's opinion.
Aluminum ducting tape is quite sticky stuff and seems to stay put. I have had my roll of aluminum duct tape (this is not standard fabric duct tape) for some time now and all applications of it has held extremely well. Granted, it has not always been exposed to high temps other than central heating during the winter, stick and brick house. We'll see how well it holds on my TT but aluminum duct tape is significantly better than fabric duct tape. Just make sure there are multiple overlapping layers applied as you are sealing off different areas.
Other... it is surprising how bad the seals can be on RV AC ducting can be. I was shocked but also realize that because of multiple years of movement, the bad seals will only get worse. Seems our AC used to work sufficiently but progressively got worse over the years. Had I maintained keeping the seals sealed up good, my AC would probably not have had to work as hard over the years. Also of note, just because a RV is new, doesn't mean the seals are sealed correctly. As the AC unit ages, the fins will accumulate dirt and bends further stressing the unit. Everything will help to get the AC unit functioning its best.
Well, at least I am in the know now.
