What to use for weatherstripping cargo door?

Greetings,

I added a cargo door to my TT to access the under-sofa area from the exterior, and more importantly, to cover a big gash I put in the siding this past fall. My question is, since the flange of the door is straight and the aluminum siding is corrugated, what is recommended to fill the spaces in the gaps? I noticed a foam/rubber material was used on the windows.

    That's what I do. Butyl tape and then I trim and use ProFlex after a day or so if letting it squeeze out.

    Throw the butyl putty to it and call it a day. You may need to double it over on itself to get it thick enough to make contact with the aluminum in spots...

    You can caulk around the edges but it's not a must. If you put plenty of putty in there, then run it down snug with the screws, you should get putty to squeeze out. If you trim that off it should be good enough. But, if you prefer you can use a little caulk to seal that edge.

    Yep. If Rangerbait means he wants to seal between hatch frame and the aluminum siding, then butyl putty is ticket. My local RV shop has it in 25' rolls where the putty is on a paper backing that you peel off as you install it.

    I replaced some seals on my trailer...got some from Lowe's. I had to shave it down some so that it would fit. It was too thick to start with...

    I use self-stick foam rubber for things like this. The foam can be shaped or compressed to fit the profile.
