We're the proud new owners of a 1995 Towlite 18-TD! First order of business is to get this baby sealed up tight and completely weather conditioned. Most of the old caulk is becoming brittle and looks to have been somewhat haphazardly applied.

Was just wondering if there is any particular caulk or caulking method you all would recommend? I've seen some places recommend corner seal tape. I think that would definitely help create a better seal, however I don't think the corner trim would cover it. Judging by the pics below, what's the best way I can make it both functional and cosmetically appealing?

Welcome to the forum. Lexel is one of the better caulks to use.

Awesome, will use those. Should I be concerned with how the edge is separating from the corner trim in some places? It seems like simply recaulking it would be setting it up for an eventual problem. Should I use butyl tape or something else to reinforce those edges?

Welcome!

Here's a neat idea. This guy had a smooth RV surface to work with, so you might have to make some modifications, but the video might give you some useful ideas.

I have read to use a hair dryer when scraping old caulking off. A heat gun provides too much heat and will melt the surrounding surface. Lexell caulk is a premium caulk and can be purchased at ACEhardware or on the internet. It costs about eight dollars a tube . Worth every penny. It is recommended that after an Rv is 5 to 6 years old all the windows need to be removed and resealed with Butyl tape and Lexell caulk on the outside. Many of us didn't know to do this and suffered extensive wall water damage. You Tube has a video on how to do this. This first window you take out is scary. Then it gets easier. With the window out you can see the wall layers/condition. It is also a good idea to replace all screws with stainless steel one.

Thank you.

Like ya said ...GREAT Idea...only thought I have is (I never used alu Tape) but it night tear if chassis flexes..Maybe Eternabond tape would be better...(just a thought)...and a layer of Butyl between tape and post material
