I have uesed the torklift on two my trucks and I think they are the best. On the 1996 the rear did bolt on to the receiver hitch and the fronts to the frame.
On mt 2007 the frant again bolt to the frame and the rear attach to the receiver hitch. the difference between the two of the trucks is that the 96 had to be drilled and the 07 ones are bolt on.
Go to the torklift site and find the model to fit your truck, or do a search and find a dealer near you. You won't be disapointed.
