Just for reference...
I hauled an 80's Chevy K20 regular cab 4x4 about 1700 miles round trip and with fuel it cost me around $500...that was using my '09 F350 with 14k lbs., 20' bumper hitch.
Also pulled another 80's Chevy K30 crew cab 4x4, pulled with same truck and trailer 2700 miles round trip and that was $950
Granted...that's on my time, and wear and tear on my truck/trailer, but it saved me lots in the end!
