i just used uhaul this weekend
and pulled a 1954 gmc long box
with my 2012 gmc sierra 1500 crew cab
drove 800 miles with no problem
you have to tell them your truck will
pull it.
they told me it would not work
i told them i had truck built to
put my 30 foot trailer
6.0 eng 6 speed trans
it worked fine for me
