In the "old days" (for me that was in the 70's)I used a 1951 chev 1/2 ton stock except for 261 and 4 speed. I had a 20 ft. long utility flatdeck tandem with electric braks.
Worked good for then but not tooo much power on hills.
Then, same trailer with newer70's Jeep Wagoneer with Buick 350.
Latest system is to rent a U Haul trailer ( my old trailer got stolen) and a Dodge Ramcharger.
Works great but 318 bit weak on hills.
