Shows how much I know!
Just for clarification the 1140 does not come with a cab as the 1100 does.
Thanks for the clarification. I just assumed that all the 1100's had cabs--but had completely zoned out on the 1140 being the 'back-seat' version.
That being the case, I would strongly recommend the OEM plastic roof. It is nearly indestructible (and mine has had some heavy encounters with overhanging trees that would have dented a metal roof and broken anything less robust). I would also recommend the glass OEM windshield.
BCZoom has raised good points about the tires. I have the worksite tires and am quite happy with them, using chains in the winter. They are not much help in mud, but I don't encounter much mud. I appreciate that they do not tear up my woods trails as much as the ATV tires would.
I also would recommend a good set of lights on the top, facing back and front. Mine were installed by the dealer and I do not know the mfr. They are simple, have a guard to provide some protection against branches, and switch on and off at the back of the lights--not in the cab. So not as convenient as some that the guys are using, but suit me fine.
I also had a bed-liner sprayed on by a local shop. Been very happy with the results.
