I own a 1989 Fleetwood Pace Arrow 35 foot Chevy P-30. I was just wondering if anyone else maybe has been experiencing my problem. My MH motor screams at 55mph. It is working way to hard to keep it at ...
Funny, he had no problem at 70 ,you have a problem struggling at 55.....HUMMM....Id say suspect something is up...so far good advice here....RPMS first..bad tune up and screaming at 55 can jive....does the motor look like its been worked on.....?
