Not sure that all the height increase is in the tires. Often they make other changes, some of which might be needed to clear the larger tires. Now, if the tires are wider, they will pull harder on pavement, but on soft ground will cut in less, roll easier.

Larger wheels and tires put more stress on everything else, I found that out the hard way with lifted trucks over the years.
You might want to check that when talking about wheels that are not driven. Much of the stress you saw was from driving the larger tires. If trailer tires are the same width and hardness, the larger diameter will roll over things easier.
(Safety regulations require taller berms on mine roads where vehicles with taller wheels run)
I've looked closely at a few on lots or at shows. Looked like they used taller spring hangers. Seen one, forget brand, with torsion axles and they stitched a 4x2" piece of tube to the bottom of the paper thin machine welded frame rail. Looked really cheesy. The point is most have frames made by Lippert and they're garbage. They're lucky to hold together if babied along let along dragging them up and down goat trails no matter what size tires are installed. Look at how the box is mounted out at the end of those flimsy outriggers. I am sure someone makes a true off road one but not sure who. It's not coming out of Indiana by Thor or Forest River, Winnie/GD, etc.
