Well...
Again, shut off your Overland Marketing Machine sir...
When traveling solo (which most of mine is) if you get stuck, chances are awfully dang high you dont want to continue forward. So a front winch would just be a cool bumper decoration at that point.
In my 20 years of off road shenanigans, i have ONLY used my front winch to extract others, almost always backwards. The handful of times i did get stuck and needed extraction, i also had to go backwards.
I almost look at a rear winch as more important than a front for my needs (dont ask why i didnt do that first, hahahaha).
I primarily see the front winch as a tool to extract others, falling trees on the trail, etc... But rear winch is for extracting myself, so i can get to the Taco shop.
A rear winch would be nice on your truck, but unfortunately, you've have a bunch of cut down melted rubber down there instead [inset kissy face]
Maybe the snow legend
@java will chime in about times hes had to extract from snow, i am guessing he went backwards.
