That Ranger would have better luck with a Taco than a ZR2 …
Towing ? I’d listen to the RV guys instead of Ford … One of the problems with tow ratings is you can drive it up with axle gearing, stiff springs, etc - testosterone rich shoppers go for it and after the first near miss they think again.
I don’t want to share road with anyone willing to put that much weight on/behind a Ranger. Already saw a Gladiator jack knifed on a curve with a twin axle RV. Boats or low CG … but many of them don’t have brakes until they too are heavy enough.
The other problem with front approach angles is cooling is impacted … the standard Duramax has a higher tow rating than a ZR2, ie DMax Canyon can supposedly tow 7700 … but I’ll credit the engineers who down grade that on a jacked up small truck. I would not plan any serious towing with toy trucks.
