I know this has been answered many times in many different ways. But to tell you the truth it is still very confusing. I have not actually purchased anything yet but below is what I am looking at getting. Can someone tell me how to evaluate these numbers and if this seems to be a good fit. TV: F450 DRW 4.3 Axle ratio GCWR: 29,000 Payload: 5700 (Still cant figure what this includes and doesn't so can figure max pin weight) Maximum Loaded 5th Wheel Trailer: 20,100 5th Wheeler Heartland Landmark Dry Pin Weight: 2150 Dry Weight: 12500 Max Loaded Weigh: 16,100 Money wasn't a major factor in determining what I wanted for a TV. I just wanted to make sure I can use it for running around in also since I will become a Fulltimer when I purchase later this summer. I would prefer a F3500 SRW but am worried it couldn't safely support this trailer. The 3500 SRW is on rated at 15,400 thus I would be under sized from the get go and if I am going Dually I figured I would go all out in case I wanted to replace the Heartland later on for something else. My main concern is being safe on the road and having the stopping power when I need it.
