The following is painful to recount even now, but this is an important topic.
RV Particulars: 2002 Itasca Horizon CAT 330 Allison Tran 6 speed
Mileage: 37,600
Breakdown Description: Traveling South on I-25 rolling in Trinidad, Co about to go over Raton Pass. Lossing power
Symptoms: RPM needle is irratic and I am losing power, managed to make into a WalMart parking lot. Checked tran fluid level is was good.
Effect: No power, could not get over 35/40 mph. Called Allison. I was instructed, if I can, drive to Stewart/Stevenson in Pueblo, Co. (80 miles away). Service manager will be there to meet us. It was Sunday aftenoon.
Cause: Tran wiring harness had detached from the frame and landed on the exhaust manifold.
Outcome: with wiring harness repaired and properly attached, all's well.
Addendum: that was the longest drive of my life from Trinidad to Pueblo.
Second, it took several hours for the tech to find the problem. Discussed with Winnebago, they were not aware of this ever happening before. On the forum, I read where someone reported that fully extended jacks can cause problems with wiring detaching. I did very much appreciate the good service at Stewart/Stevenson and that Allison paid the bill.
