I'll take maintenance over repairs, every day of the week. But really? I'm not selling you one either..... BUT. Its not about maintenance or repairs, its strictly about buying the machine for the tasks, and I'm telling you I've seen enough of your scrounging wood pics to know you're going to bash your head against the ROP cage enough with a tracked machine, that when I tell you the Wheeled machine would be ten times more often, Im not exagerating. You just aren't going to be happy with a wheeled machine in those Off road conditions you have. Heck- you could go cheaper and buy a tractor/FEL and do better in the offroad scrounging, than with a wheeled skiddybopper, but you'd have a lot of mud on your wood, constantly.
You have all the skills you need to maintain an undercarriage- you dont need to get scared about it, its not that tough. People that complain about it, are probably beating on their equipment, not maintaining it, and are beyotching about REPAIRS.
I run my ASV on half throtttle. You know how many experts have told me its not good for hydraulic pumps? SO many. Yet here it sits, with ZERO pump issues after 17 years. My Bobcat went almost 20 years, 10k hours, and never once opened up the motor or the hydro pumps, never. 8 sets of tires at 2k per set. My ASV just got new tracks at 15 years with ZERO tightening, and had tons of tread- and they were not loose in the slightest, which is why I recommend ASV. The molded lugs sheared off due to dry rot in one weekend all on one side. (the Rubber lugs are 90 durometer and integrated into the 70 durometer track at the molding process) I didn;t complain, I had the new tracks in two days from one state away at $2k OEM.
I'm a bit of a "expert" on equipment, because ( I am lazy) I have a background of using all kinds for many different construction experiences. Marine construction, residential and commercial construction, land clearing, environmental construction and remediation, road and bridge construction. Lots of specialized iron have passed my hands. I've never done anything by hand I can find a piece of machinery to do for me. I've bid and taken jobs solely to pay for the piece of equipment I wanted to use on the job, paying for labor from another business or out of my own pocket- thats how lazy I am (and creative at business financing).
You will not be happy with a wheeled unit off road, it will simply beat your ass to death. Another thing to consider- the cost to ship being what it is, you'll be paying for it twice when you have to buy a CTL after buying a wheeled unit. PLUS, when you go to sell the wheeled unit, the market is going to be tough to find the buyer IMO.
