Great post, I enjoyed the logic run through. From square one I was figuring you'd be in great shape, until I saw how little your chassis actually weighs....remarkably light! My chassis weighs so much it feels like the camper could weigh a lot more and not worry about tippy ness but I really am surprised at your low weight. Glad my guess was right at least, you sure won't have an issue :)
I remember Doug Hackney posting a nice thread here where he did the same sort of calculation but after he had assembled his rig. As I recall he used a forklift and scale and lifted each corner to a specific angle (or maybe just measured the angle) and measured weights and got a pretty darn precise measurement of his vertical COG. I would be interesting if once you assemble the rig to do the ACTUAL measurement and compare against your prediction. Doug was doing it to get a feel for what sort of side hill angle he could drive safely.
you've added a nice contribution here, thanks!
