I have a cheapo Hymer Sunlight Van One on a 2017 Promaster chassis. We bought it last summer and have put 6,000 miles on it. I get about 17-18 mpg and it does everything we want. The ride is decent, it handles well, we overnight sometimes in a truck stop and enjoy the ease of using it. I have the second alternator that acts as a generator and lithium battery set up for using it to run the fridge and the invertor. I have had a class A and C but with the two of us this is ideal. Go to Carado and Sunlight or Hymer Aktiv and wannabes. You will have to ask to join but they are not picky. Also check out the Promaster forum.
