I agree with the guys who said that they wished that the bobbers would use the lesser trucks if they will be cut up. I TOTALLY understand, however, why they don't. They want a clean truck and the cleaneast intact trucks will result in the cleanest bobbed trucks. With that said, man, find a tractor to bob. Tractors...nice ones...are all over the place. I have no idea what you paid for that M813, but I would bet there would have to be someone out there who would give you $7-9K for it.
I completely agree that one day these trucks are going to be more scarce. It is hard to believe now, but the guy with the 65 Mustang analogy is right on. The XZLs are a perfect example of scarcity. For a while, NO ONE wanted anything to do with the 1600s. I have been looking for new XZLs for my HEMTT for almost two years, but I had a h*** of a time finding them because a lot of the guys are putting them on their 5 tons (bobbed or not) and bobbed deuces. Anyway, the "run" on XZLs really caused me some problems finding them for my HEMTT...the correct truck for those tires. I finally found a set of eight brand new XZLs...but it took a while...and I had to pay out the a** for them. I am not trying to cry on anyone's shoulder here; I am only pointing out that part/truck scarcity will, and does, occur!
