Old class c vs New class c

I'm currently looking for a class c motorhome and I have come across an interesting dilemma. I have found a 1976 Ford Cobra. The odometer says 38,000 but is only a five digit odometer. The cab is super clean and everything looks good. I also found a 1992 Chevy motorhome, with 113,000 miles. My question is, is it better to go with the newer one with (assuming) higher miles or an older one with lower? I have worked on old car and understand the plethora of problems one can run into, I mainly just don't want to purchase an older class c and have some mechanical issues but I feel the same thing could happen with a newer one at 113,000 miles. Any recommendations, is it all fairly subjective?
