I have the same setup as Bart; Air bags on the rear. I really like this setup. No equalizer hitch for my Argosy 26. Round numbers my truck has a 4400# front axle and a 6000# rear axle. The GVW rating of the truck is 8800#. The truck; full of gas with me inside weighs 5900#. That gives me a payload capacity of 8800#-5900# = 2900#.
Maybe that's why this rig handles so nice. Loaded and ready for the road my trailer weighs 5500#. It is a 1998 Dodge 2500 long box extended cab 2 wheel drive pickup with a 5 speed manual transmission and a 360 V8.
I believe the long wheel base truck gives me considerably more stability when it comes to cross winds etc. The trailer is 26' hitch to bumper, the truck is 23' bumper to bumper. Pretty good match in my book.
I run with 50# of air in the air bags and 65# of air in the truck tires and 45# to 55# in the trailer tires. Depending on if the trailer is dry or wet.
I never drive over 65 mph.
