My wife and I use ours to portage in our stands and feeders, we have some terrain that's certainly not what I'd call friendly, plus under-brush and areas with a LOT of dead-fall to navigate.

If you can walk it, it can roll it. The only time you'll get into trouble is in snow cover or thin mud where the wheels will sink. I bought a double wheel kit for mud, which seems to work quite well, and I rigged a set of ski's from a wrecked snow machine for the snow, also works quite well the few times I've used it with snow-shoes (obviously not in KS).
