Reese Dual Cam installation

My brother just bought a new used Hybrid and he asked me what would be the best hitch. I told him I really liked the DC. I gave him the part number for the proper one for his trailer and the dealer said "oh you don`t need that" he wanted to sell him one of the new Reese hitches with the new friction pads that the WD bars ride on. I said the DC is far superior than those so he insisted on it and the dealer finally gave in and ordered it. I believe it`s all because they can be time consuming to install! We are going to install it this sunday. maybe I`ll take some pics of the install so all the dealers can see the proper way to install one and take notes or use them for reference!
