Well, the price is at least not outta line, but in my opinion those Vader-style machines are junk. As Scott pointed out you have to shuttle the trailers all over the lot while still leaving room for people to still move around. Most companies don't want you doing that for insurance and liability reasons. Then you can't wash the wheels(which is very important to the eye to give the appearance of being clean) or the running gear, and if it has a refrigerator on it you can forget it. You won't get that area clean at all. Plus I feel that they do a crappy job anyway. And another thing: If they have trailers there's probably a very good chance that they have tractors as well. Then you need more equipment to wash those. It looks like a big yellowish orange boat anchor to me...
