Heavy duty hitch extension??
I have a Mega Cab dually Ram that I use to tow a 15K race trailer. I want to get a camper for the truck, but the highest capacity hitch/extension setup I can find is the Torklift. Their extension is ...

I can't show you the math, but I can tell you that extending your hitch length has an enormous effect on tongue weight. Think of a lever and the leverage effect. I think the physics of it is sort of the reverse of a weight-distribution system.
I'm sure some of the engineers on this forum can jump in here and explain mathematically what it is that I'm referring to.

Yes, it drastically increases some of the forces that can be applied to the truck.
Problem is people see the static hitch weight and don't understand in real life towing, there are dynamic forces involved where the hitch weight and the lever arm come into play.
5th wheels tow very well because the hitch sits right over the axle and can't apply any torque. Bumper pulls aren't as good because there is typically 3-4 ft where the hitch can apply leverage...now add a few more feet and with a very large bumper pull and it just gets out of hand real quick.
Even in the static condition, that's likely going to add 3000lb to the rear axle, so with a big heavy truck camper, good chance the rear axle is overloaded even on a dually.
As someone else said, get a shorter truck camper, so you can use a standard hitch or move up to a commercial truck with drastically higher capability.
