I lost big patches of the 1/4” insulation that was actually between the framing and the metal skin instead of inside the framing. I’m going to do 1” rigid foam insulation inside all the framing but I’m wondering, do I need to replace the 1/4” insulation that was between the framing and the skin as well? I haven’t found a rigid foam this thin so if so, what would you recommend using?
You can see one of the missing sections here, the insulation is a thin layer of pink stuff over a white Styrofoam type stuff.

The skins need to be removed to see what you have. Trailers are rebuilt from the outside...

Trust vikx on this. There is definitely rot you won't be able to repair from the inside. Take the skin off the one side and you will understand what we're saying.
Some videos worth watching.

I used this picture because it shows where that strange insulation is missing better than how the trailer looks currently with metal off.

I'm glad to hear you have the skin off. No doubt you will lose most of the insulation between the skin and framing when you do the repairs. I insulate but don't worry about between the frame and skin with Tyvek vapor barrier over it. Show us what the camper looks like from the outside with skin off and you may get other suggestions.

NC is correct. I've never heard of 1/4" insulation in a vintage trailer. Show us where it is from the outside. Maybe we can help.

Ya, the yellow is only about a 1/4" fiberglass (not much use but beats nothing I guess). I'll try to dig up a picture from the '67 Compact to add. Mine was laid over the framing before the interior paneling was attached to it. Just mashed it between the framework and wall panel.

Hi, From a vintage trailer guy located in Santa Ana, CA. It's good to see lots of activity here.

Seems to me that questions about building new wall framing would be more important on a trailer that needs a full tear down and frame up rebuild. This trailer will require lots of work before any thought of plumbing, electrical wiring, or insulation and vapor barrier is necessary.
The photo shows an example of a gutted trailer, this is the very worse case example for a new builder. After the interior panels were removed, you have really nothing left to use as a template to build back.
