bingo.. all of thatYeah, the Ranger had issues in development staying cool. The truck was designed mainly for diesels with mechanical fans not boosted 4cyl gassers and they had problems getting enough air in the little grille to cool it so they went old school with a real fan.
Being a clean sheet design I would think they made the grille opening big enough to cool whatever with the Bronco.
Another thing is warranty claims. The diesel gladiator may not be rated as much because they don't think it will stay together well towing that much weight.
The old Rangers, a manual had about half the tow rating as an automatic. Same frame/brakes/springs whatever so it was not a safety thing. Ford didn't want to be replacing clutches under warranty. There is more to it than just springs and crap, although for an offroad vehicle I suppose the Bronco is going to suffer... just like most offroad oriented vehicles (Wrangler, Raptor, Power Wagon etc)
