Not from somewhere else, Kurt, just one of the several "Super" variants around Las Vegas. That one is probably one of two that Williams Tank Lines bought a couple of years ago from a carrier that either went under or sold off a bunch of units; there are several like that around, with Williams, Rebel, Haycock, KAG, and a couple of other haulers. They are just a bigger variant, having a larger tank, thus the second steer axle; most "Super Tankers" have a 5400 gal. truck tank on a regular chassis, and pull a four axle 8000 (+/-) trailer. Then, there are the "Trains"; a semi of around 9200, sometimes even more, two or three axles, plus a trailer (pup) of around 5400 to 8000 with two to four axles; they run these thing mostly between here and Salt Lake City, and in northern Nevada and all over Utah. When my son had his own truck, he was running trains that way, and drove "Supers" for both Williams, and KAG. The gas hauling business here is really rough, though, and he couldn't make a decent living, so he went on the road in a walk away lease with Prime, hauling refers; tripled his take home pay.
