I installed the hitch myself in 2006 and then again in 2008 in a different Dodge.Its a fairly easy install in my opinion.The first time it took about 5+ hours,I was in no hurry and made sure everything was right.The second installation took about 3.5 hours after removal from the 2500 Dodge.
Just lay everything out and read the instructions and be sure you have a high quality 1 3/4 inch metal hole saw and a good electric drill (ac) The Dodge installation was easy due to the existing frame holes for the rear mounts (underbody)
I've used the hitch for over seven years and have made only minor tension adjustments to the nylon block, along with routine maint.These are very durable hitches that lock fully around the pin.My hitch came from Tweetys also and was delivered free to my business address.
Enjoy your new hitch.
