I am not going to gut mine, because it is all original and in good condition. I will some day get a smaller unit and gut it, or buy a gutted one that someone lost interest in. It costs a bundle to redo one and do it well. Big bundle.
I'd like to redo a Safari, seems to be the right size and an easier layout. They started making duall axle Safaris in the 70's, I believe. I prefer the dual axle over the single, for stability reasons.
Anyways, if youor trailer is nice enough for you inside, then I would not gut it.
