Always make sure the "accommodation" (floor plan, storage, kitchen, bedroom, etc.) will work for you. Then check the load carrying capacity that it has, once you factor your passengers in. From all reports, the Promaster drives well, but its single rear wheels and probably an overhang added by the RV builder, bring its carrying capacity into question.
