My 02 pulls a 20ft tag along 2 5/16 ball with load equalizer bars, with 18K-20K pounds from Lexington Ky to Pie Town New Mexico. I haul complete log cabin kits and put them together on site. The truck does fine but only gets 9mpg. but that is a hell of a load! It only warms up a bit when climbing from 5500 ft. elevation to 6800 ft. Its a long haul !! I usually pull over and let her idle for a few minutes until the guage begins to fall then complete the pull.
Running home empty with a 4500Lb. trailer I get 14mpg. No trailer I get 19-23 mpg. if I stay below 2000 RPM. She has 253K miles so far.
GO BOWTIE !!!!!!
