Sorry Piston, that Curtis cab shouldn't be considered, even if it did have A/C... the M62 simply isn't going to have a factory cab. They'd have to do some serious re engineering to get a cab that could be heated, cooled, and didn't fog up the windows. It lacks the enviromental separation that's designed in from the beginning anything less is a bandaid fix that's way overpriced.
It's aggravating for me as well, I rented a Komatsu for my dozer operator I thought it was an open cab, nope, it's a full cab with A/C!!! That's okay, I just keep pulling the A/C fuse
. I tell him that A/C burns too much diesel. He keeps bringing replacement fuses to work everyday. I gotta save money any way I can, it was 95 today!
