Well here's an update. I did the plywood to level the bed from the B&W hitch, I tightened the tie downs hand tight, I aired my tires up to 70psi, I made some overload extensions (took less than 30 mins and made a huge difference) last night, and aired down my airbags till the overload bumpstops were just barely touching the springs (roughly 40psi). Surprisingly my with all this done the truck measured out to be level. Best of all, the camper now feels like it's one with the truck based on my 2 mile drive to work. I still have cabover bounce but it's not as pronounced and sway is practically gone. It feels more like a uhaul truck as opposed to feeling like a 1/2 ton with 2 tons of junk in the bed.
I'll be able to better assess the changes when I drive to my folk's place this evening. I'm just happy to see it on the truck again. :D
