An auto car on a tow dolly?

A trailer with trailer brakes is one thing and a dolly is another. But I had a 99 Dakota 3.9 that I towed a Duster 300 miles on a dolly...and a 72 Challenger on the same Dolly from Kentucky to PA almost 800 miles lots of steep grades but not like yours. Other than gas mileage the truck worked great.
