I always here people talk about how owning a tandem itself does not make you money, its the convenience factor of it. What does that mean? What is the convenience factor? Can someone explain. The guy I bought the 150 from has given me a month to decide if I want to buy his 84' autocar tandem with 425k miles and a 20ton trailer for $20k. He is giving me a package deal price because I bought his excavator. In september he needs to renew registration and insurance on it, so if I do not buy it soon, he can not give me the 'package price". I figure with some one driving the truck, factoring insurance, reg, and fuel I would need to run 550 loads to break even. This is not including any repairs. 550 loads is about 2 years of deliveries. Its not including haul outs or equipment moves that will cost me $300 a shot. Right now I have no proablem getting whatever material I need in or out. But guys are telling me when things are booming it could take a day or more to get a truck in. Right now I get loads from the quarry on a hour notice. I just do not know if I want to be bothered by owning a truck.
