Overloaded or wrong truck?

A monster truck camper with 1000-1500lb 6-8ft behind the axle gets rocking, it can put drastically more bending force on the frame.

It may visually appear that way, but the EC 1165 does NOT put thousands of pounds that far back from the axle.

Google its COG: 61.5", or roughly 5' measured from the front of the bed. That puts it right on, or a hair behind the rear axle.

Let's say it's 6" behind the rear axle: 6000 lbs x 6" = 36,000 in-lbs of moment. Assuming the typical hitch ball is 4' from rear axle, 36k in-lb/48" = 750lbs.

So the bending stress of a EC1165 is the same as 750 lbs of hitch weight. Who'd worry about that on a modern dually?
