I don't think that he was towing more than 17K when he toasted the ring and pinion either.

I remember Charles saying that..........might have even been in one of my threads. IIRC he kept burning up all his u-joints in less than 150 mi. also.

I am just surprised that anyone can tow 17k in a race tune with no issues.

I agree with Cleatus, not the best thing for the rest of the truck!
