Just got done installing the running boards on my truck last weekend. I have a 19 1500 rebel with the rebel 12 package. It was a fairly straight install. Removing trim panels was the hardest part. If you can install a car stereo you can install these. The instructions were detailed enough. The only thing I found lacking was information on how to install the wires into the connectors. It showed the location but not the orientation. Not to worry though they can only be installed one way. I had a friend helping and it took about two hours.
I have the air suspension and set it at the off road height and did not need to remove the wheels for the install. It was $1400 at my local dealer with the 15% off coupon. Price to have it flashed is $95.
