I have the Andersen Ultimate for my TV and was using the adapter in the rear facing position. Had to set it up that way to keep from hitting the sides of the bed because I have the pin box as low as it will go on the 5er to try to get to level. If I faced the adapter forward, the pin box would hit the side of the bed.
Having it set facing aft means the 5er is closer to the back of the truck and would hit past 60 deg or so. So I went nuts and ordered a Curt 4" offset gooseball. This moves the Andersen back 4". Now I have enough clearance so that the 5er can never hit the back window. I was worried it would move the pivot point too far aft but that actually worked out ok. The Andersen ball was 2" forward of the rear axles before the offset and now it is 2" aft. Will make a trip to the scales to see what impact that has on weight distribution, but not today. 50mph winds.
I'd post pics, but the aren't very interesting and I forgot to take some. Here's an image of the Curt offset:
