Does this rig have the 3 or 4 seats upfront? If so, they might be included under a recall because they were never properly tested under US or CA law. Confirm whether this year is included. Checking the VIN probably shows this. And if it is, has it been remediated. Step one is the removal of the seat belts to get it removed from the recall. Once they are removed, there is a kit to fix it. It is very expensive and not covered by any warranty. (seats must be removed... everything underneath also removed... seats reattached to comply... everything underneath put back on. I believe that the cost was something like $2000 per seat)
Parts availability shouldn't be an issue since the new Roadtrek, Inc. plans to continue to make this model.
