Last Saturday's offroad trip convinced me that wireless will not be the way for me. A Jeep lost reverse going over an obstacle, and needed to be winched back up the hill to set aside for the return trip. The guy winching had a Warn winch with wireless... he could not be in the cab of his jeep to operate the winch, there was no control, as it was sporadic. Maybe the radios or some other electronic device was interrupting the signal, but too much risk there. The winch remote operated just fine outside the Jeep, and we got the Jeep off the trail.
