Long ago and far away I had a 19 foot tandem axle self-contained travel trailer. I have no idea what the thing weighed, but since it was a late 1980s trailer, it wasn't light.
I had three vehicles at the time that I towed it with; a 1970 Jeep V8 Wagoneer, a 1976 Ford E150 Club Wagon, and a 1975 Dodge Ram W250 (3/4 ton 4X4).
I had a WD hitch, but the only rig I used it on was the Wagoneer. I had to have the WD on it to keep the back bumper from dragging on the ground and the headlights on the road instead of in the trees.
I had no trouble at all towing that trailer without the WD hitch using the Ford or the Dodge.
Now I have a 7X14 enclosed trailer that I haul two ATVs in. No WD hitch. No problems.
