Throughout my 7 years or so of wheeling:
Had to replace 1 driveshaft u-joint on the drive out to Moab
Broke 1 front 297-x u-joint (dana 44 joint)
Replace 5 Napa lifetime alternators

Broke 2 valve springs, one resulting in a dropped valve

Broke a 1310 yoke/u-joint
Sheared the bearing journal off a 12 bolt detroit taking the ring and pinion with it
Twisted the rear driveshaft into two
Broke a dana 60 30 spline stub and Warn lockout
Distributor kept dropping spark which is FINALLY fixed

Broke a 465/205 adapter
I need to replace the starter thats in it now
Mystery electrical problem that resulted in rewiring the truck from scratch
That's all I can think of for now, though its only HAD to be on the trailer a couple times.
Basically I'm really lucky if I'm not working on the truck right up to the minute we have to leave
