Sorry, can't make a recommendaiton but my Cadillac came with remote start and I love that freaking thing! If my wife gets in the car before me and I hit the remote start, it scares her every time! LOL!
It'll cost more upfront, but save yourself some future hassle and try to have the dealership install it. If/when you sell the truck it will look better to have had them install it.
I have a 2011 F150. I purchased the ford remote start, installed it myself. Had to have the dealership turn it on through the computer. Cheap, especially considering I ended up with two more keys/keyfobs
