I worked at U-haul while in college for 2 years. 26' is the largest truck they have. The diesels were always a "big problem" because of stupid renters. In winter after telling them to plug in the truck overnight because hey, it's 15 degrees outside, they didnt. Then they would call us and complain my truck wont start, I woulda pluged it in but I packed the extension cord and it's in the truck. Then we would have to send out someone to help them at big $$$$. Or you would have the customer who would use starting fluid to get the truck started because he failed to plug it in, which sometimes worked. That ruined the glow plugs, and anyone who rented the the truck after that guy couldnt start the truck below 40 degrees and we have no proof who did it, $$$$$ to send out a guy and replace the glow plugs. You also had the dumb customers who would put gas in the tank, which did a job on the injector pump at best. I will say U-haul trucks are usually dirty and in need of some help, but every once in a blue moon you get an O.K. truck. Their trucks are the best designed rental trucks with their features, but doesnt do much you much good as U-haul neglects them. Uhaul has one advantage over the rest, you can rent trucks in small towns when the other guys are nowhere near.
