In three weeks i am going to be towing my 1974 K5 (minus engine/tranny/transfercase) using my 1985 Suburban with a 350. I have installed a tow bar on the K5 and will be towing it from Los Angeles to Salt Lake City (approx 700 miles). The K5 Has 33" X12.5" tires and i was wondering if any of you out there has any towing advise for a complete novice. I am worried with regards to the K5 drifting in and out of lanes!! Thanks in advanced for any help.
