How many miles is to many for an early '90's B

I bought my 97 Dodge with 94,000 miles and would not hesitate to drive it anywhere. I have had only one minor fix that all Dodge vans of this era will go through. The throttle control valve became fouled and causes the vehicle to run rough until the engine warms up easy fix. Takes a few minutes. I went ahead and changed plugs and airfilter. I would not however buy a big class A or class C with that high a miles due to much greater stress on the chassis.
