So, my hunting buddy shelled out 27k on a new muddox this year so we could go into some serious backcountry. Well, with 20 hours on it, the coupling from engine to hydraulic pumps failed. Luckily my buddy was only 3 miles off the road on a caribou hunt before our big moose hunt. So the Alaska muddox dealer had a new coupling sent up, installed it at their shop in anchorage, and my buddy went back out to test it out. Half hour off the road, the coupling failed again. The sad thing is, the dealer in anchorage doesn't even have a service manual to work out of. Steer clear of these machines.
