Here is some history for you. Tiger motor homes is or at least was owned by the founder of Four Wheel Campers. The original one was a van conversion. I have the opportunity to see one when I owned FWC in Woodland. The customer stopped by our shop and it was surprising to see how much the interior matched a FWC camper. It even had the same lift system for the roof.
I never had the chance to talk to Dave, the owner of Tiger, but I did talk to his manager back then and Dave is retired in Florida somewhere.
Looks like they have changed over the years since then from the website that you posted.
Sincerely,
Ben
