I think Budget is cheaper with the discount codes.
I`ve rented trucks from Uhaul a few times. They are ok so to speak, but there are better companies out there I think.
Penske is the greatest, they guarantee the reservation and have nice new trucks.They'll price match as well.Get them to price match and say you do not have the AAA discount. After they match call up and say you have AAA. It'll put down the rate even more.
