Motorhome & dump truck collide

Actually, if it "rolled several times" it says a lot for the construction. Most class A Motor Homes, trailers and 5th wheels would have disassembled. As to real world performance, I have not found an uphill interstate grade that it will not maintain 50+ with most RVs slower in the truck lane and the DW does not appreciate everything in the cabinets stacked at the back when accelerating. Just sayin' this is not the realm of 0-60 in 3.9. Bets are passenger was not belted in and took the rolling ride bouncing inside.
