The story is in Canada - In the USA it is called Hot Shot towing. A Ford F 350 can tow close to 30K. - you see a lot of hot shot towing with Car carriers, boats, etc. Lot of videos of F 350’s or Ram trucks towing an empty 53 foot trailer.
Yeah, but sometimes those things aren’t what they appear.
When the Marine Corps got rid of the Gamma Goats there was a Gunnery Sergeant at Lejiune who bought a surplus engine and with a little finagling (I believe he had to move the firewall several inches) stuffed it into one of those wide bed Rams.
