I was towing a 2019 GMC Acadia. Weighs about 3900 pounds. Hitch was rated at 8000.
All hitches are rated for a straight pull without a drop. MorRyde welds the hitch to the frame adapters and then to the frame itself on my coach. Where it usually tears is in the frame adapters and not the hitch itself. Usually it is the bending moment from the excessive torque caused by the drop. I tow three different vehicles on my 350 lb Master Tow dolly with surge brakes. I use a Roadmaster spare tire carrier mounted to the standard hitch with a 1" riser. The vertical load in the receiver is 100 lbs from the tire and 29 lbs from the dolly tongue. The vehicles towed are 2,800 lbs to 3,500 lbs. So far no problems with my 2016 Hurricane's hitch in 42,000 miles.

Lippert is a parts supplier to the RV industry. Lippert is not certified to modify Ford chassis. It is MorRyde Internationalm who makes Airstream chassis and modifies Ford chassis for Thor Industries. In actuality Detroit Chassis assembles the F-53 and E-350 chassis for Ford. The F-X50 chassis and cabs are built by Ford in Ford's truck assembly plants.
You are correct. That's the company I was thinking of but had a brain fart.
Most of these hitches are installed by LCI during the frame/chassis prep, and done very well. What I've seen with the hitch issues posted are the use of drop hitches causing the problem. Hitches are rated at a pure lateral load with the assumed ball position 4 inches from the outer, receiver "ring" of the hitch itself. Extending the hitch beyond this reduces the capacity by 50% (etrailer and a few other hitch manufacturers). Further, dropping the hitch 6 or 10 inches creates a "fulcrum" or "twisting" effect, causing stress on start ups and when stopping. The standard for most applications is approximately 18" from the ground. Most of the hitches installed on these commercial chassis' (higher than a light truck setup) are much higher than 18", requiring some type of drop.
Love your responses.
Next problem I can't figure out I'm going directly to you.
