Im a little confused by your question (I get confused easily
) . What are you towing? I had the factory 5th wheel package installed and im not using the other holes either with my fifth wheel. I was looking at price. I think it was approx. $400 seemed very reasonable with a clean look including the whole setup ready to go. But, if i knew about the brake controller i probably would have decided otherwise. I wanted to be able to use my bed (which you can do with a fifth wheel in there, but youll break your back removing it). My andersen hitch weighs around 45 pounds. I had the dealer throw in the gooseneck hitch as part of the purchase deal with the truck (cool little kit that comes with the bag in the photo and has the hitch and the safety chain attachments which i never used cause i dont have the right hooks yet . Thats why i went with the andersen. I can easily remove it and throw it on the garage wall when i dont need it. Plus it easily pulls all that weight with awesome smoothness! I couldnt be happier. You have to consider your future needs also. The brake controller will work on a smaller trailer but not one like mine, so depending on what youre towing and what you need......
Oh btw, you can get approx. 90 degrees with the andersen and not hit your truck
