Seat belts are only part of it, what about air bags?
Our class A has seat belts on the side facing couch, but because of the side force on the passenger in a collision, I think they may even do more harm than good.
We had a 5th wheel and crew cab truck when the kids were small. The cab may have had all the safety equipment, but that 17,000 lb 5er was coming in the cab in a forward collision and no cowboy rack was going to stop it. I really always kind of cringed at the thought of that and never really felt we would have a chance.
I watched on the "Big Time RV" TV show about some folks with the exact same concern you are having. They settled on a large Class B that had 4 forward facing high back automotive seats and the van had airbags in the front if I remember. The back seats turned to face a table when parked.
