Air bags would do the trick, SumoSprings would also as a one and done, nothing further to mess with. RAS is an option.
WDH isn’t needed. The front rising is a result of the rear drop.
I added SumoSprings to my F150 for towing without a WDH, IF I can watch the tongue weight keeping it near or under the 500# factory limit. The combo tows my 4K# TT pretty level but I still encountered a tiny wagging feeling on the interstate at 65mph. I have a decent WDH and will use it for interstate travel but with the SumoSprings, sag is minimal & I don’t need theWDH ON local or country roads driving 55mph. “Cue Sammy Hagar”
