I find it hard to sleep in the cabover when off the truck. I worry about this too much to get any rest. Until I get a firm foundation in facts/data I will continue to worry. I guess it's time to investigate thoroughly. With the Admiral and myself it is every bit of 400 lbs. up there, although I won't go into a further breakdown of our respective weights.
I have been wondering about off truck use since I got it and need to contact Northwood to get the facts. If I do get any official info I'll post it. Until then some investigation and testing may be warranted. Of course, I'll be watching this thread as well.
