I will challenge that.
‘26’ foot U-Haul trucks are NOT 26 feet ON THE FLOOR. They are only 23 foot on the floor, and the other ‘3 feet’ is over the cab & NOT down to the floor from the ceiling.
The U-Haul trucks have quite large wheel bumps which are quite awkward to load onto.
The Largest 26’ U-Haul trucks only have a PAYLOAD OF 7400#.
HOWEVER:
Penske trucks are a full 26’ ON THE FLOOR.
The roof is translucent, so you have some light when you are loading.
The PAYLOAD in the 26’ Penske truck is 17,000#. That is 215 % of the U-Haul truck.
The quotes I got for U-Haul trucks were more than 72% higher than the Penske trucks.
I am renting Penske trucks for my move.
Penske trucks may be Diesels while UHauls seem to be gas.
UHauls rates seem highly dependent on start and destination city pairs and time of year. Also, UHaul seems to have more destination dropoff points and a lower load floor height.
YMMV.
