I considered doing this on my TC; however, I built a place in the bed that would securely hold my Honda EU1000 genny/inverter or Generac 4KW genny. At the risk of topic drift, may I ask which model of Warn winch you just bought? Sounds like a great idea.
Sure, it's the Warn PullzAll winch/hoist, rated at 1,000 lbs. It also comes in battery powered model, but the rep at a recent trade show admitted the battery system is not optimal.
