An outfit I worked for years ago had a late 60's GMC 7500 with a 476? Magnum V-6 with a 610 roadranger trans. Single drive with a 5th wheel and every sort of rear hitch you can imagine. Also had a Skagit knuckleboom we affectionately called "Dribbles", Man that thing could easily leave a 427 Chevy or 534 Ford in the weeds. Gas mileage... well it got the job done.
