Maybe I started out with a real truck
The Op said he wants to adjust his head light beams... that his trucks hauling capacity was fine.
Airbags work for that just fine. I don't lose air winter or summer (where did that come from)
My airbags are 11 years old, we have 70,000 miles, 49 states and most of Canada, 1081 nights traveling... and coutless day trips with a very big camper
I don't fix what ain't broke... I don't break my stuff by adding junk just for the hell of it.
Some have a propeller in their hitch reciever... I don't!
