The sad part is, running gear upgrades do not show up in too many camper brochures. You can not sell it, if it is not offered. Some are finally coming with rubber equalizers, shocks and I even saw self adjusting brakes but they are far and in-between. I have yet to see an adjustable axle seat even though they have been around a long time. And they still keep using these light duty hangers and frame attachments.
Just maybe RV trailers are built to the specs required by their weight and usage factors. The engineering analysis for RV trailers does not require a background for self propelled vehicles. Engineers for the RV trailer industry come from the same schools as those designing cars and trucks.
Take a look at pages 27 - 30 in the reference. Looks to me like that's a pretty good explanation of a simple system to support an RV trailer.
