MH or TC - Which is better to get into the Boonies?

My Tiger Class C MH, built on a Chevy 4x4 pickup chassis, is perfect for the boonies. It is 87 inches wide, just under 9.5 feet tall. You won't get much smaller than that unless you choose a popup TC.

Larger MH's, even the 24 foot you mentioned, are taller and wider. Where I go, size usually is more important than having 4WD. I do use the high clearance often and the 4WD at least a bit on every trip.
