I completely agree, with the possible exception of one of the original design criterion for the platform - the 18" vertical wall climb. I'm not saying it absolutely wont do it, I'm just not SURE it would do it without the reduction.
That said - for the typical civilian use case such as an overland RV application - I don't see myself dragging my living space over such an obstacle. There's virtually always a better choice - go around, make an earthen ramp, cut a section out of the log, tow it or winch it out of your way, etc, etc. In a combat environment there are use cases for going over (possibly to the detriment of the equipment) debris, wreckage, curbs, short walls, etc where it would be non-feasible to have a bunch of grunts with shovels jump out and make a hole for you.
These trucks will never make good rock-crawlers. Get a tow-bar and pull your stump jumper behind it
