Won't make much of a difference if its broke (and the equipment usally is), except for documentation purposes, if you rented it from a satellite location. Most of those people are just there to rent the equipment, not fix it. If it's broke, then they have to call U-haul's service dept. to send some dumbshit out (2 hours later...while the customer waits) there to attempt to fix it (he's stupid, so he won't).
We were a satellite location for U-haul (rented Heavy equipment, and the occasional U-haul) and the equipment constantly had shit wrong with it. I usually just fixed it myself because: 1. it was quicker. 2. I wanted the stupid customers (most U-haul customers fit a certain profile) out of my lot as soon as possible, and 3. I got tired of the U-haul 'mechanics' asking to borrow my tools, or asking how to fix something.
Go find a Budget.
