My Son-in-laws 1500 crew cab didn't have a hitch on it when he bought it.
We installed the heaviest Class V that etrailer offered,
is it overkill for what he will ever tow yes. For the minimal difference in price
why contemplate lighter duty hitch.
This hitch can go through the corrosive rusty weather here in the northeast
for several years and still be able to handle any trailer he would hook to.
It took a couple of hours to install,
yes we dropped the spare tire down out of the way.
