Fender measurements, how is this possible??

[pdqparalegal1]

Hooked new TV to TT in driveway today. Old TV 2010 F-150 w/tow package. New TV 2016 F-150 long wheelbase HD tow package. I'll try to attach door sticker. Numbers with truck sitting in driveway.
front 35 5/8 at wheel opening
rear 37 3/8
with trailer attaches no bars
front 36 3/8
rear 35
with bars hooked up same as old TV trailer real close to level.
front 35 5/8
rear 36

Trailer is under the gross weights by a good amount based on Cat scales on old TV and new TV has a higher load rating.

With bars front comes back to empty measurement (35 3/8) but rear is still down 1 3/8 in is that possible? Get a child to stand on their head to read you the numbers

I`d say your good if your front is back to the unloaded number. Your rear is down alittle but that's ok, you want the rear to squat a inch or 2 .

I would say that you are pretty good. Yes the rear is down but it is still higher than the front. My personal experience with F150s is that with every generation the ride gets better and the cargo capacity goes up, they accomplish this by making springs progressively stiffer. The rear of truck will squat pretty easy with lets say the first 750 lbs, but they next 750 lbs you put in it is won't drop as much.

That's exactly what you want. I assume you are puzzled as to have the front an be back to original height, yet the rear is not back to original height. The answer is that not all of the TW is transferred to the front wheels. Because of the way a WDH works, some of the weight is also transferred back to the trailer axles.

By lifting the bars, a very large torque is applied to the hitch head (and therefore the truck's receiver). This transfers weight to the front wheels. But that force lifting the bars has to be supported by something. That something is the snap up brackets (or L-brackets, depending on your WDH), which is on the A-frame, 2-feet behind the ball. That load get's to the ground thru the frame, to the axles and wheels.

So, if you were to measure all axle weights before and after engaging the bars:
Rear axle wgt decrease = (front axle wgt increase) + (trailer axle wgt increase)

The main point is that your front height is back to stock, which means your front loading is pretty much back to stock. IMO, you have a perfect setup.
