U-Haul car trailer experience?

The worst stories ive heard about u-haul trailers are tire related. Give them a GOOD look.
Ive never used u-haul trailers myself, tho i did rent a box truck a couple times for my business.
I have a nice car trailer that I bought 25 years ago, and a box truck we bought recently (for dirt cheap. Illegal in Cali, wonderful in Az) to move three households from Cali to Az.
