Gotcha. That brings up another issue... You can't really air down 19.5" tires. Most brands the minimum is 45 psi. I researched this extensively a while back, because I was considering moving to F550 running gear. Buckstop makes a super-single conversion for military off-road tires, usually used for brush rigs, but I don't know if that's a feasible conversion for a motorhome.

Are you willing to downside a bit? An E450 4x4 conversion with 20" light truck wheels and tires, is probably your best combo for beach driving. You can run wider tires that will allow a lower psi, and you'll be ~5,000 pounds lighter to start with.
This one is from U-Joint Off-road, and the other option is QuadVan.
