Yeah, I figure a 20k winch and snatchblock would suit me well. PTO-drive seems like an easy implementation for the front, but if I want to use it at the back (and I probably would) I imagine that'd be more difficult?
For me, having these things isn't so much because I'm doing some extreme offroad in my skoolie. It's more so that I'm inevitably going to come across some rough roads, and the places I like to go - while no more difficult than some of the stuff you might take your bus on - are really, really isolated. 700km north of the nearest human settlement kind of isolated (various parts of Northern Quebec, Yukon, BC, and Newfoundland). So I don't want to go overkill, but I also want some insurance because I'd have to be 100% self reliant.
