I have recently purchased a 31' bunkhouse (8800lb GVWR) and am pulling it with a 1999 Suburban 2500. I have anti sway bars hitch etc. I am getting a bit of porpoising when riding down an interstate when going over bumps. Aside from that it tows great. I just bought the Surburban and the previous owner did not replace the shocks, so it's unclear how old they are.
Advice from the airstream dealer service guru was to replace the shocks and to insure the tires on the Suburban are LT type with the thick sidewalls indicated by the higher air pressure capability (80lbs). The tires meet those specs.
The local Chevy dealer suspension guru suggested seeking advice from others with similar setups to see what has worked, rather than experimenting with various shocks.
Thanks in advance for passing on your towing wisdom, so I avoid having to build up a lot of trial and error experiences.
