I understand perfectly and think it's a great idea. That's what Casita
does in their Liberty model, and your longways Little Joe
bed set-up is like a smaller version. Downside is single post tables can be more wobbly.
My B-van has a single-pedestal table with a piece in the pole that screws tight in the base for less wobble. Hard to explain, but it works well. It also doesn't get stuck the way some friction-only pedestal tables can. Let me know if you'd like more information.
