My RLC rear bumper is installed, I had Main Line Overland install it for me, since I really didn't want to fight with it by myself, and cut the plastic. They did a great job, not cheap, but they were great to work with. They called or texted me every day to give me a progress. Overall they were very impressed with the bumper, and I have to give them a lot of credit for installing it without any instructions.
Issues:
* Parking sensors didn't fit in the existing holes, the holes are too big. I told them to leave them uninstalled, just put some plastic plugs in the holes for now. I will figure this out on my own. The harness will need to be extended at the outer sensors too.
* I didn't have them connect the rear lights, I'll do this as well. The seller included some cheap lights, I may upgrade to some Rigids when I get around to hooking them up.
* I left the swingout off for now. They wrapped some tape around the spindle, then some rubber hose with zip ties.
* My bumper did not include the fillers at the ends just behind the rear tires, which I don't like. I just got off the phone with James (nice guy!) and he is sending me a pair to try since he has 2 bumpers in the shop now that he is building. He said he is reluctant to include these things since sometimes they don't fit, the clearances can be tight. So no promise that they will fit.

Other truck they had in the shop - This RAM was a monster, a highly custom rig first built by AEV, then MLO did the camper fitting, fuel tanks, a few other things.
