Is Uhaul the worst Moving Truck renting company?

I have been reading all kind of crap about the Uhaul trucks and how shitty they are and how bad Uhaul customer service is.
I am going to drive one of these on a 4700km trip pulling my car behind.
For some reason I don't feel too bad about that, when I read the complaints about Uhaul(they are a lot!) many of those comments are made by ladies and some are talking about stuff that does not make too much sense to me. But there are enough genuine negative feedbacks posted on the internet to give you a chill in the back, anyways next week, middle of the week, I will know what is with Uhaul!
