For what it's worth, I disagree. It is my opinion the weight distributing hitch is well worth the investment, even if you were using a 1 ton truck. It's not so much the amount of tongue weight vers the capacity of the truck, it's WHERE
that weight will be carried, on the bumper, which is about 2 feet behind
the rear axle, and that is the problem with not using a WD hitch. The WD hitch as we all know, just moves that weight farther foward on the tow vehicle, and drastically improves the ride and handling of the rig. Unless it was a fifth wheel, personally I would not consider towing for any length of time, a 29' 5000 pound trailer without a WD hitch. But, that's just my opinion.
