We setup our small round table in the front, whenever we are camping.
Our larger, rectangular table is rarely setup in the van. But we installed some short (12-14"?) fold-able legs and use it outside, with our lawn chairs.
About a year ago - I bought a 1990 Pleasure-Way based on a GMC 1-ton chassis (350 FI, Turbo 400 and 12 bolt), with 235,000 KMs (about 145,000 miles). It's built like a tank - the same chassis is used as the base for much larger vehicles.
In my opinion - the absolute number of miles on any vehicle is *far* less important than how it was taken care during that time...
