Our m116a3 is a flatbed. I don't think a matching color would look good on it, so I am having it painted gloss black. If it had sides like our picture, then yes, it would like nice. I think your friends matching paint scheme looks great. We do have a M1101 which has sides, but it is a 2011 in perfect condition, so I think I will leave it camo for now. Also the M1101 is 1460 lbs. empty. Even though we have the 285 hp engine in our 2014 Jeep Rubicon, I think the fuel economy would suffer with the weight and aerodynamics.
We have a 2012 Ford F250 with the 400 hp 800 ft. lbs. torque diesel engine, that will pull our M1101 and not know it is there. When the paint job on the M1101 gets weathered, then I could have it painted to match our F250.
