BIGR:
I am in the same boat as you. I have a Terry kind of like 88gmctrucks Nomad likely about the same damage:

And a mid 70's Apache hard side pop that's all there, got it from my sister pulled it out of the woods. Just don't have the enthusiasm to fix the popup when the Terry would be about the same effort. I haven't accessed the damage lately on the Terry its a ways away at my moms.
BTW anyone interested in restoring a classic popup? Lets make a deal. Its mainly rebuilding the lift mechanism clean paint fix cracks in the pvc, replace fabrics, table top and other odds and ends. They are really cool when fixed up.
If it turns out the Terry needs a nearly not worth it huge amount of work (thinking of you 88gmctruck

) I would be tempted to salvage the frame and fittings and use a GlenL plan to build a new coach on the frame. I suspect that would be faster than a rebuild working around the existing stuff. And have the coolness of a well made new trailer that looked like it was a classic but have modern guts.
