I have done two mine was the first and it went smooth and took about 3.5 hrs and that included the air bags. the second was for my boys 2012 ford F150 that one took about the same time for the hitch and that thing is a monster 12k with a longer throw because of the very short bed. was harder then for my Dodge with the 6.5 ft. bed 16k. we put air bags in his the following day. they don't fit, the brackets are in the way. we had to trim the airbag bracket down and then we welded them to the SG bracket and they then worked perfect not a real do it yourselfer for most.
