Why not conduct these kinds of tests with a 'real' RV?
A flat bed trailer (goose neck hitch) and a load of bricks???
Put a full sized fully loaded - say a Mobile Suits - on these trucks and take them into the mountains with long up and down grades, and into very hot desert with a strong cross wind and have at it.
I agree. 35mph up the grade with no wind resistance? Toss in the wind resistance of a high profile 5th wheel loaded to advertised max tow rating and let's see if these heavy haulers live up to their hype.
