doctor17 is an unknown quantity at this point
foam board insulation

I am currently taking all the aluminum skin off the trailer as i found a little spot where water was comming in. Not taking any chances if there will be more so i am going to seal the entire camper again. I plan on taking all the fiberglass insulation out and replace with foam board insulation.
My ? is, which foam board is or seems to be the one to get? Or are they all pretty equal in the insulation dept. I also plan on taping all the seams.

Can't help you with a recommendation, but I'll bump you back to the top of the list.

There is a big difference in foam--R value as well as exterior/interior. Go to or another big box and search on styrofoam to see a lot of what's available.

JohnB is on a distinguished road
See here what "Frank" did when he built his brothers camper. He did an outstanding job on it...

Here he is doing the floor insulation

And here are the walls. See the post after it too as he sealed the gaps

Your looking for close cell foam, not the normal little round balls of Styrofoam board.

The R value will help guide you

Good luck and curious to see how yours comes out.
