In all honesty, I am not that well versed in towing. With that being said, I am trying to educate myself as much as possible in the art of towing, learning the weight ratings, tongue weight, etc as well as trying to decide whether to go with a bumper pull or 5th wheel. I do not want to overload the truck by any means, and i dont want to bite off more than I can chew. I will be traveling all over the country, for either my or my girfriends jobs. I believe, after looking at the hitch, it is just the heavy duty and not the max tow package. I saw the chart last night farther up in the thread and I can say that my truck has all the equipment stated in the 535 column. My question is this: if i were to simply add the trailer brake controller and swap the hitches, would that give me the max tow package? Im not sure what the difference is in the bumpers, or if that really matters to the tow value itself...
