I'd agree. I wouldn't complain about my factory hitch if it would do 10k GTW / 1k TW without a WD system. I'd just tow and be done with.
That's the part that's still in question, though. From what I understand, the problem with tongue weight is not when "at rest". Instead, it's when you're moving. Actually, when you're trying to STOP moving...
During braking, the hitch part of the trailer can "dive", placing significant additional tongue weight on the tow vehicle. This, in turn, increases weight on the rear axle and decreases weight on the front axle. Enough shift in weight distribution and the situation can get dangerous.
From conversations I've had with the trailer dealer (who also trailers his Deere 4xxx around), I'm not likely to have any significant issue for a number of reasons:
- I'm going to be trailering about 4500 pounds of cargo on a 2700 pound trailer. I won't be at or even near the max rating for the trailer or the truck.
- I have the ability to take some of the tongue weight off simply by backing the tractor up a little on the trailer and shifting the weight a little more toward / over the rear axle of the trailer.
- I will not be towing far or traveling at any significant rates of speed.
Being smart about how I load, tie down, and drive, I should never have any issue with tongue weight for my vehicle. Additionally, I've had 2+ yard of mulch in my bed, fully compressing the rear springs (meaning about 1200-1300 pounds in the bed), and the truck never felt like it was "squatting" in the rear. I realize that having more weight applied *behind* the axle is worse than what I had *over* the axle, but I don't believe I will find myself in that situation.
He told me that I could certainly add a WDH at any time if I felt like I needed it there. And, he said I should consider one if I will ever need to trailer for any significant distance.
