Need info on mid 90's p30 or 32 chassis

I used the recommended air pressure for the weight of our MH, which worked out to be 80 PSI. I did not like the way it handled. I increased the air pressure to 90 psi and the handling improved. Remember the recommended pressure it the minimum that you should run, increasing the pressure can change the handling characteristics. For us, the increase made it less susceptible to being thrown about by passing truckers and it did not want to hunt as much.
