They are not good either, few locations to pickup and drop.....and few equipments available.

when i went through your post, i found that you tried to change your reservation at the last hours........it is hard to find new equipment in the last hour becasue all trucks and vans are busy in service. especially in the week-end, you even  can not find anything available.

U-haul dealers are not U-haul, they are just part time or side business......that's the reason all the dealers are not customer friendly.
