Recently I towed the biggest load I've ever pulled with my F250. Let me say that it did well for how heavy the load was and considering the circumstances.
The tractor is a Ford 6610 II Special. It has a water in all the tires. Attached to it is a small cutter. Because of the length of the tractor and cutter and the length of the trailer, we had to move the tractor all the way forward so that everything could fit. My Grizzly 550 ATV had to be in the bed of my truck.
The 5.4L and ZF6 manual transmission did well towing the 30 mile trip down country roads. If I could do anything over again, I'd put my 2 5/16" ball on my shorter drop hitch. I had it on the 5" drop but the tongue load was really too much for that drop, so the trailer pointed slightly "nose down."
My rear suspension was nearly on the jounce bumpers.
Here's a pic of the whole load.
Now that you've seen the pics and got the anxiety out of your system, it's time for the good, the bad, and the ugly.
Low gear in the ZF6 is awesome. Even with the base engine, getting this rig rolling was a breeze. Even as we towed the trailer through the pasture and off road, it the deep 5.79 ratio really helps get things moving.
The trailer brake control was fantastic. Despite a less than perfect load distribution, stopping was good. Gone are the days when we'd pull a loaded trailer behind our half-ton pickups with out ABS; you'd hit the brakes and the front tires would just lock up and smoke. Not so here, even with a suspension that's "squatted down."
The "E" rated MT/R Kevlars can handle this kind of weight with ease. Talk about a tough tire, it didn't belly out or squirm around despite the rear suspension being dang-near bottomed out....
No weight distributing hitch and too much drop in the receiver for the load. The trailer could have been more level.
Seven (7) miles per gallon.
My truck is not set up to tow like this regularly with a 3" lift and 35" tires. And good thing I like waving... to the cars passing my by. 60mph was doable, but going up hills on those back roads made my rig lose speed quickly unless I could keep the engine churning 4500rpm. (which it didn't mind one bit. The water temp never climbed over 200deg on my ScanGauge)
All in all, it was a success. The tractor got moved, not body got hurt, and my truck didn't blow a head gasket LoL
