Question for the guy's with duallies and big campers

I thought about trying to do this with either the Fuso (or its competitors) or a Benz Sprinter chassis cab. I found the Fuso's ride quality to be - let's leave it at "undesirable" - and in either case you end up with something that is quite tall. The cabover cab is considerably higher than a pickup, and the sleeper part of the camper has to clear that. The advantage is that the overall length will be considerably shorter, with or without the camper.
