i need a class 111 trailer hitch for my 98 dakota. i've called around & i'm getting a price of about $300 for the install. i checked etrailers on the net & i can get a draw tite or hidden hitch for about $110., not including the ball mount or wiring harness. has anyone installed a hitch themselves & is it worth the hassle to do it myself? according to the site the hitch will mount up with no drilling required. anyone installed a hitch themselves & did it mount right up? i don't want to do any drilling. also what's the better choice, the draw tite or the hidden hitch? what's the difference, if any in the 2?
