How much PSI???

Got a pressure sprayer here and a coach that has some REALLY filthy spots. I know that HI is WAAAAYYYY too much pressure to use but what psi settings can / would a guy use.

Bad locations are the roof roll over where it blends into sidewalls. Got me stumped??

    Start w/ the least - you can always (slowly) turn it up....
    stay away from any seams, joints, seals or other objects where water could enter.

    That's a tough call. I have a power washer but don't use it on the MH...don't want to take a chance on doing some damage or driving some water where it should not be.
