Except for the fact he is 500+lbs over the rear axle.Recheck your math, you are over but not as much as you think.
1633 and 1724 is 3357 and 1550 plus 1990 is 3540.
Difference of 183kg or about 400# unless I am miss reading somethin.
You need a lighter deck like an LPI.
How much your deck weigh.
I would have thought the new aluminum fords would be legal with two sleds.
No gas and no chains and you should be legal.
Your truck should have between 2800 and 3200# payload according to ford specs. Can't see where you used up that much payload????
Lay off the cheese burgers bud! lol
I am also surprised that you can't haul two sleds let alone one!
But then I am not privy to your trucks factory setup.
