This ^^
The rear is a different height for starters, the 4x4 slightly higher, which raises the tongue of the trailer and distributes weight differently, and bam, instability. Not using a WDH is the second factor. I had a 14 RWD, towed my current trailer with a Husky RB WDH, and towed beautifully. got a 2016 4WD, same cab, same bed as the 14 and pretty much the same weight, and the setup used on the RWD truck had the 4WD all over the road with the same trailer. Even a complete re-setup of the hitch didn't correct it. The new gen trucks can be real squirrely if not properly setup.

Tire pressures were 5 psi under max for both trucks. I think his has 18s (lariat) where mine has 17s (keys wheels and no floormats edition)...
We'll figure out what the results are after he gets a WDH... don't think we have scales that can weigh stuff by axle nearby.

The hitch weight(according to what i could find) DRY is 705 lb and the trailers gross is 7300. So 2 tanks and a battery add another 100lb, crap stored in front of the axle add another 100-200 and factor in its a toy hauler and they are already tongue heavy to compensate for the garage payload, he NEEDS a WDH for the 700-1100 lb of TW. I used a harbor freight 1k/10k with just a friction bar that would cost around $200 and it worked for years, you have to get some weight back on the front end in these light weight trucks.

I did some basic calculations using base curb weights for each truck and surprisingly the 4x4 2.7l regular cab 8ft bed truck will carry its center of gravity nearly 6 inches further forward then the 4x2 3.5l CC 5.5ft bed truck. That may seem insignificant to some but it makes the difference. Ask the fifth wheel guys how much a few inches makes on pin location. You put the same passengers up front and not much changes but let’s say you add 400lbs of gear up against the the back wall of the bed of each, that would give the regular cab a bigger advantage. Unloaded the SCREW 145 WB carries 300lbs more on the rear axle then the RC 141 WB. YMMV with different loading conditions.

The 2.7 is a short 6.5ft bed.
And I am one of those 5th wheel guys
But I don't have to use a sliding hitch like the short bed 1 ton brodozer guys.

bumpy roads are the worst, and can't wait until the new one arrives! Awaiting the paperwork to make the deal with Ford official and get the check too. I keep wondering when the passenger seat will fall apart now that the counter vibration block fell out. That seat shakes like mad.

My tires (reg cab short bed F150) have 30k miles on em and are fine. His have less than 3k on em... better not have a blown up belt, but yeah... I would think he would feel something unloaded too. We'll see how the WD hitch does when that comes in; So far the only difference I guess is that the 4x4 f150 and the tahoe are heavier in the front...
Oddly my dually didn't notice any issues pulling that same 20 footer when I had it; and that's a 2wd too. wonder why (j/k)
