Paul,

Two things. One, Jimmy is right, have someone put gauges on the unit to see if you have excessive head pressure. That will cycle the unit frequently under load and kill the clutch.

Second, and I saw this problem on another coach, the clutch is not getting twelve volts. The low voltage is caused by the long run of undersized wire from the front. Check the voltage going to the clutch, and if it's under 12 install a relay setup to get full voltage to the clutch. The low voltage draws high amperage which burns up the clutch.
