    Yep, that's a way to do it, but it won't be 100% correct. Truck scales measure weight on the axle. Since the ball is further back it's getting leverage on the suspension. I bet you weren't as high as you thought!

    Think about a gooseneck trailer vs a bumper pull. You can put way more load directly over the axle, but it doesn't change the rolling resistance weight of a given trailer. My little single cab 1/2 ton Chevy sags about 2.5" with the boat hooked up, I'm at 650# tongue weight (usually pull with my wife's megacab, super long MASSIVE truck plus a long trailer), but I have to load almost 1200# of horse feed in the bed to get the same sag out of it. That's the reason airbags work, it's a midpoint in the seesaw effect.

    You can see the trailer is just touch nose down on my truck, but I hate swapping balls between trailers.

    Okay, I think I'm kinda tracking with ya. Leverage, fulcrum, and some interesting geometry...

    On my last boat, I was able to actually put both axles of the trailer and the tongue jack on the truck scale at once. so I was able to find out what the trailer weighed by itself and also hitched up. I figured the difference on that was obviously tongue weight.

    But on the XLV, it was too long to have the tongue jack on the scale along with both axles... so I had to do it how I described above... Too bad I don't have free access to the scales at the garbage dump, because those are LONG!

    In Oregon, on some highways, they have truck weigh stations that are seldom staffed. They actually have the scales operational at all times so you can just roll up and weigh without having to pay anything or anyone messing with ya. It's kinda cool.

    My sister uses one of these for her horse trailers, they're not 100% accurate, but close enough for government work... lol
    She has a couple different trailers and this makes it easy to know if she should shift s horse off the axles depending on how much tack and feed she's hauling too

    Default To all you guys that tow with half tons.

    And the answer is to get a leveling system. Poor handling comes from front tires not being grounded properly. You can see that even the SA does not squat the Tahoe that much because of leveling system.

    If concerned about brakes then switch to electric trailer brakes. I would also suggest having brakes checked on trailer. I had a loose line. After the trailer shop worked them over and bled them properly wow! I have great trailer brakes. They made the comment that many surge brake systems do not get bled properly at factory and never maintained by a customer.

    This link has a nice summary of the different brands and their conventional (non W.D. hitch) towing capacities. It is from 2015, but from the Ford info listed from the OP and my own research into the GMC Sierra I want it, seems fairly accurate to today still.

    Yes. Gm calls it magnetic ride with leveling. Not sure on Ford. It will cut out a lot of the lean when turning and overall squat.

    That's probably the meal ticket for me. I pulled her up from storage yesterday and hooked up to the new truck for the first time. Not as bad as my old truck, but it's definitely got some squat.
