Stay seated and buckled in for the most part. My DW will make short fast trips out of her seat only when on straight and smooth roads. If not on one we find a stopping spot. Ran into a man and granddaughter several years ago who'said spouse was out of seat when he hit a bump in the road she fell backwards into the wind she and dash area, hit her head and they thought broke her back. He stopped in a construction zone and workers there summoned a helicopter flight to the hospital. As turned out no broken back but it has been a reminder to us to stay seated and us extreme caution if must leave the seat.And: in a big accident your RV will crumble into unrecognizable peaces. They are very fragile compared to semi's.
