Landgreen, we are on the same page on both ideas.
This past summer I also had 1 two man crew and 1 one man crew. I am considering just sending out 3 one man trucks. I have the equipment and trucks already.
As far as trucks go, after running all 3/4 and 1 ton trucks for the last 12 years, I have recently purchased a couple used 1/2 ton chevys for mowing crews and they get much better gas mileage and have no problem pulling the equipment.
