Looking at a Chevy Colorado at 4500 lbs.
I worked for, and retired from, a very large Defense Contractor.
One of our contracts was to design, build, and install electronic equipment into a handful of Blackhawk helicopters.
Not having a real tug, for over a year we used a 2WD Jeep Cherokee belonging to the Maintenance Dept. to pull the 18,000 pound Blackwawks all over the flight line and in and out of the hangar.
True, we were not out on the Interstate at 70 mph, but it worked for us.
Another part of that same project was to design and build a HMMWV towed trailer and mounted 3 meter, fold-out, dish antenna system.
The unique 5,000 pound trailer hitch had to be designed with a 250% safety factor.
To prove the safety factor we loaded the HMMWV up to 12,500 pounds and had a crane lift the vehicle off the ground by the hitch. All 5 passed.
I would bet that, for liability reasons, ALL vehicle mounted hitches and suspensions are built with some safety factor, probably at least 100%.
