This product seems extremely dangerous to me. I have towed travel trailers for over 30 years and have learned that keeping the ball as close to the tow vehicle is very important for stability. The physics of all this is: the further you put the load behind the rear axle, the more unstable the tow vehicle becomes. 41 or 48" seems awful far to me. The trailer has all that leverage on the tow vehicle. Moving the center of gravity back too far in the tow vehicle is how you lose control and roll them over.
Yes, we all know and understand the physics, but we are not towing travel trailers here in general. The extension is a necessary evil for towing behind a long slide-in truck camper, which can overhang the rear of the truck by as much as 48".
This is a commercial product and apparently it is not as inherently dangerous as you claim because if it were, Reese would not offer it, as surely someone would have brought a significant claim against them over it. One million dollar settlement, and the product would be gone because they don't sell very many of them.
