OK, Rant Time. U-Haul has maintained their 100% perfect record of delivering equipment (trucks, dollys, trailers, etc.) with underinflated tires !!! Employee told me " they didn't have an inflation gauge" WTF ?!?!?!?!? Guess what, I DID !!! Employee proceeded to thump trailer tires with a stick and proclaim "...they're all fine..." Quick check with my Ryobi inflator netted anywhere from 47 psi to 56 psi. They grudgingly agreed to top them all off.
Lesson: NEVER assume U-Haul has properly inflated tires on ANYTHING on their lot. Same goes for equipment maintenance like properly lubed tire strap ratchets (HA HA), broken or missing ramp pins, etc.
I once rented a U hual trailer that pulled funny. When i checked the tire pressure they ranged from 20 to 80 psi.
The last time I rented a car trailer from Uhaul, the vendor made me wait while he checked everything, including tire pressures.
