FWIW, I'm currently running these Monroe Load Adjusting Shocks:
Can't say enough good things about them at $90 shipped, they apparently add 1k of resistance. When I lower my full tongue weight on the hitch (CAT scale confirmed loaded tongue of 860 lbs), it only squats to a slight forward rake, nearly level. This is before I engage the WD hitch.
With my e2 hitch, I can return the front end of the truck to unloaded height. It tows very well. No bottoming out or porposing.
