Thanks for your responses, Penski in Kansas City will rent a straight truck for the purpose of CDL testing just long enough for the test and back to Penski for $250.
Ryder will cost less but you must wait a week or more for the truck to come available.
I did find a man though the testing...
I am in need of a straight truck with air in the Kansas City area to finish my class B CDL skills test. Does anyone here have a suggestion as to where I should look for a truck with air for a day?
