You really have to figure out what fiver you want. There are so many variables with regard to weight. One fiver may have a 2k pin weight and another about the same length might have a 3k pin weight. One may have 12k dry weight and the same length might be 16k dry. Remember the advertised weight is unloaded you will weight more once everything gets in the rig. One word of caution you will find dealers lots filled with 3/4 ton trucks and a sales person will tell you that that truck can tow anything. There is a big difference between being able to tow and being able to stop and control. Figure out your trailer needs then go truck shopping. Don't make an expensive mistake and buy the wrong truck only to find out later you need something else. You can never have to much truck. Good luck
