We installed ours on a 2014 Ram CC diesel longbed DRW. Left the wheel wells on.
It was an hours-long PITA. We had to call Torklift several times. First there was some kind of coating on the bolts that was so thick, the nuts would not fit. We had to steel brush/scrape most of it off. Then the clearance issue: Torklift finally told us to just cut the bolts shorter as there was zilch clearance for getting them in and then being able to get any kind of wrench in also.
I ranted in a post about it and how they say in their video: "So easy your wife could install it" or something like that. They saw my complaints, told us they would inform engineering about the design, and sent us 2 free Torklift hats. I also suggested they come up with better instructions for specific makes, models and years.
We are not UNhandy! Just FYI in case yours isn't smooth either.
