For any future folks looking, i have the even smaller "standard bed with ram box"on my 1 ton SRW, short version, works like a champ!
Now i DID add a 4" offset gooseneck on the bottom to make sure it was far enough back, and also mounted the block backwards(kingpin in front of the ball receptacle). I will post pics and try to explain my reasoning, but basically the length of my bed wasnt a problem with the hitch, the width becomes an issue when turning due to the distance between the bed rails with the rambox system (4' if i remember right). So the pinbox doesnt rise in angle fast enough not to hit the side when turning, so by mounting my block backwards when i turn it kind of moves the front of my pinbox more to the other side of the bed and in turn allows the back of my pinbox to clear my bed rails.
Again i will add pictures when i can take some, and try to provide an illustration explaining some of the logic behind what i typed out. I do also want to take more measurements and see if i have extra room to eliminate maybe my extra 4" offset. I bought the camper 6 hours from home, so i could only research hitch options and take what i knew would work, since it worked and pulled well i havent ever gone back to see just how much clearance i actually have. I can assure you i am REAL close to 90 when i back it into my driveway, and have never touched anything anywhere.
