Pleasure Way with high miles vs Roadtrek with low miles

The number of miles on an RV is more of a function of the chassis and how well it's been cared for over the years. The diesel Sprinter is typical German engineering - usually over-engineered, over-complicated and over-priced. But kept in good shape they run for a long time.

And as has already been stated, build quality of the Roadtrek (especially around the 2006 timeframe) was pretty abysmal. I owned one and learned a lot about RV maintenance and repairs from the ownership experience.
