I live in the Mat Su valley just a bit up the road from Wasilla, a lot of hunters are building aggressive go anywhere hunting buggies up here cobbled from anything and everything.
I have seen them on novice welded frames of old rebar with an old cab of some kind, seen old military trucks with DC-3 tires under them and even myself I am building one possibly this winter. It will be armored for the “just in case” situation of an attacking bear. It will have a carcass winch and a sizable meat chest possibly with refrigeration or just dry ice packs.
Oh, man, that sounds like just the ticket!
