Re: Great West Van Ride-Rite suspension
I had a Sprinter van with the air bag suspension so don't know if recommendations would translate. I was running 50 psi after experimenting. I think you'll get different opinions. Over the years I have read so many different ones. Your own opinion would be the best. What I would do is find a road course with enough variables to see how the suspension is affected and drive the course with the different psi's. You might want to do it with someone sitting in the back end for a second opinion and maybe do each twice trading off driving and sitting in back. Loading makes a difference too.
