I run my 2002 Plus8 at 21psi. If loaded up with a passenger and luggage for a trip I put it up to 23/24psi.
I have AVO shocks from New Elms set at the lightest setting but do put them up a couple of clicks for the heavier load trips.
I take a small compressor along as a back up to change psi if needed.
Basically trial and error starting at , say, 22 and make small changes as you get the feel.
What rear shocks do you have? Adjustable?
I put AVO on after my Kohni’s failed. They were the type that had limited adjustment that was done off the car. Also a known weakness internally where a heavy bump could damage the adjustment.
I am tempted by Roger’s bump stops as a future mod.
