Hell, I raced a vette, steel chassis, and it got to rock clrawing a
couple times. :) And boat trailers are regularly towed over uneven
ground.

With only 1 wheel in contact with the ground while the boat was loaded and
tied down and the tow vehicle at tilted in the opposite direction?

I doubt it.

"Uneven" is a long way from "rock crawling" and your 3,400# boat is
unlikely to be towed over "Jeep" roads on an all-Aluminum trailer with any
regularity.
