Different way to take your car

many years back I was looking at some toy haulers on a C chassis, can't remember name, fun seeker/finder?? but google let me down. they had three models, the two lesser ones were fairly standard C build, but the big one was on a different chassis, there was a wall behind front seats with a crawl thru opening. I think the main problem would be the weight on the ramp door wouldn't work. would need separate ramps like aaussie one.
