Hi Jedidad,
I agree with you in that a class C (and B+) are safer in a frontal crash. They would also be safer in a side-impact crash into the van doors, but every motorhome manufacture cuts the van's roof as shown which significantly weakens the door frame where the seat belts attach. The door frame and all, pivots in towards the person sitting there. The saving grace with the tall-sitting van is that most vehicle bumpers will impact the floor where it is also stronger. But the rig in a roll-over would be surely be threatening.
Regarding the class A example you provided, I really doubt it is 24 feet long. You might want to add a couple feet to that number....maybe even more.
Our rig
CLICK HERE TO SEE IT true measurements is 23'-8" long. It is not much different than the floor plan you seek, but with a reduced living area. We ordered ours without a slideout, but most
Phoenix Cruiser 2350s made, have one. BTW: If you are counting inches like we did for fitting the rig in our garage, the Ford van of the current style with the dump truck look, was introduced in 2008. It is 3" longer than our 2007.
