I had my MH serviced for the season yesterday at Holt CAT in San Antonio; overall it was an excellent experience. One thing worth noting is that it took them nearly 3 hours to locate and have a new serpentine belt delivered when we decided mine was cracked enough to warrant replacement. I figure that if it took that long in a city the size of SA, then it would be much tougher in small, more remote locations. I already had a spare which I decided to keep for emergencies since it is a couple of years old, but I suggest that anyone not carrying a spare get one. Remember, these are not CAT belts since the chassis-builder creates the fitment.
Although I don't know if all Thunders of the same year use the same belt, but mine is a Gates K081153 whose primary fitment is Ford 650/750 trucks of vintage 2000-2001. I found the following online source which is a bit cheaper than what I paid the CAT dealer:
