Off the point of this discussion, based on his scaled weights the pin weight is 2000 lbs which is fine for his 2500. I know manufacturers state "1/2 ton towable" but how could his trailer be considered a 1/2 ton towable as the 2000 lb pin weight would exceed the maximum cargo weight carring capacity of all 1/2 ton trucks.

Almost all. My 2013 F150 with Max Payload is stickered at 2,592#.

If you have that # then you have the HD payload. Not just the Maxtow. Big difference between the two. Like 700+lbs more.

My Gasser Dually has right at 4000 lbs payload...

OP.. I zoomed in on your pic and I suspect this hitch is slightly behind the axle. Here is my zoomed in pic..



Thanks!

Your F150 can carry more than my 2013 2500 diesel (2475 lbs) or my buddies 2013 F250 diesel (2550 lbs) another buddies gas 2010 F250 (2650 lbs) is only 58lbs more. I guess we don't need 250 or 2500 anymore we can just buy 1/2 ton and carry more weight then our 3/4 ton trucks?

Would you really want to??

I do see there are a couple of flatlanders in this group, I just pulled home from the Oregon coast, with all tanks partly full,just too nasty to drain at the SP, heavy rain and strong (25 to 30 mph with gust to 40). Did actually felt a couple of the gust when next to the open water, but no change in direction or lane position.
These is a reason a 3/4 ton 2500/250 weighs much more than a 1/2 ton 1500/150 truck, that extra weight makes the truck most stable. Honestly this drive didn't feel any different than the truck feels on a nice sunny day with no wind.

I have stated before there are 5ers that the right 1/2 ton 1500/150 can safely tow, but I would not trade the feeling I have with my 2500 with 3500 suspension. Soft ride in a truck comes at a cost!

I was expecting some possible chucking with four partly full tanks, but didn't really notice any, and this is a 2500 without bags, or Timbers stock Camper special suspension.

Do you have a slide bar hitch if so may be your problem. Weight should not cause chucking but a loose hitch or parts will. I went to a lock jaw hitch and no chucking.

Half of that could easily be error in the scales, if not all of it.

Your numbers appear to tell a different story than what you indicate.

The front axle decreased in weight when ready to camp tells me that the hitch is behind the axle rather than in front of the rear axle. The picture looks like it verifies this too. This could be a major contributor to the problem of ride comfort.

How are you making the determination that the hitch/pin is ahead of the axle? One way is if you have a 4x8 sheet of plywood - rest it against the side of the truck (connected or not) and align the sheet with the rear axle. Then determine if the hitch/pin is ahead or behind the line.

Truck Scale Weight (Full tank with me and my wife no camping gear in truck)
Steer Axle = 4780
Dive Axle – 3220
Gross Weight = 8000

5th Wheel Scale Weight (Load to go camping)
Steer Axle = 4700
Dive Axle 5220
Trailer Axle 6840
Gross Weight 16,760
