Recommended pressure for air bags?

This appears from a google picture search to be a typical class C on the Ford or Chevy van chassis. Towing will make relatively little difference since your tongue weight is a pretty small fraction of the total vehicle weight, doubly so for flat towing the Fit.

It's hard to give a hard and fast rule about this; the general idea is to put enough air in them so that the chassis is riding at an appropriate ride height, neither bottoming out nor staying at the top of the travel. (The instructions generally suggest measuring ride height unloaded and then adjusting to match when loaded. That doesn't work very well on a class C since you're always pretty well loaded from the point of view of the chassis.)

On my motorhome, somewhere around 40 psi seems to work out pretty well. Others have reported quite different pressures work for them. It probably depends somewhat on how worn or stretched the main springs are.

Hi, my 2008 Winnebago Outlook 31C came with air bags. I need to check the pressures on them. What pressure should I try initially for running when not towing?

Is this Workhorse chassis, P32?

15 or 20 lbs. You need to keep some air in them so they hold their shape or don't get pinched. Otherwise enough to level the rig but not more than their stated capacity.
