Folks should probably be careful with how much weight is being stored up there in the cabover area when going down the road.
Even though the cabover bed area is hopefully designed to hold a couple of adults when parked and camped ... bouncing down the road with anywhere near that kind of weight up there has got to be hard on the coach's internal walls and the framing structure within those walls. Considering all the troubles Class C owners have with leaks in their overhead bed areas, IMHO one should not carry much weight up there when traveling.
I keep our overhead cab area lightly loaded with just my sleeping gear when going down the road. We have a basement model Class C with plenty of head room up there in the cabover bed area. I get down from the bed by facing out into the coach and putting my left foot on the stock ladder's flat rungs and the right foot on the dinette seat. So far (I've been around for over seven decades) getting up and down the approximately 4 foot ladder has been no problem. Since we have a basement model, our outside storage cabinets can actually hold enough such that the overhead cab area is not needed for raw storage. We fold up the overhead bed when traveling, anyway, so as to leave the ceiling area open above the passenger and driver cab seats for easy access in and out of the cab.
