In your original post I see that you have a 2014 Four winds Class C they come on a Ford Chassis or a Chevy Chassis and you didn't say which one it was on so all the posters have assumed it is on the Ford Chassis. So just in case it isn't I will give
you a look at the sticker on a Chevy Chassis
I run 65psi in the front but 75psi in the rear, a little less than the max. After experimenting I found that this is the best combo.
I find that it handles very well. Being on a Chevy Chassis it isn't plagued with the handling problems of a RV built Ford Chassis.
