A former neighbor (now deceased) and his wife drove an early-60's half ton Chevy with a 235 3 speed from Merced California to Tennessee in the early 1980's, towing a huge 2-axle trailer loaded with all their worldly possessions on it. He said there were a few times he had to drive a few feet uphill, have his wife jump out with a wheel chock to keep the rig from rolling backwards, and let the old engine rest awhile, then repeat the process. I was amazed he made it around the block with that rig, let alone travel 2500 miles! The trailer was badly overloaded, and the truck bed was full, as well.
