Sorry it took a while for me to see this thread, I've been out enjoying my Maule (nosewheel).
I won't approach the nose/tailwheel discussion; there is nothing to be gained there.
I've had my MXT7 180-A about 1,000 mostly trouble free hours, and I've flown in about a dozen other Maules, sometimes piloted by some of the best backcountry pilots I've even encountered.
My 2 cents is that a Maule needs horsepower to live up to it's potential in the backcountry. Although my 180 has a high useful load, it's a pig at higher weights with respect to climb, especially high and hot.
Same applies to a C/S prop. I have a FP and wish I'd spent the money for a bigger motor and different prop. Of course there WAS no more money!
There are a few mods for a Trigear to make it a bit tougher off airport. The nosefork will accomadate a 7" wheel, 8.5's can go on the mains. A rubber snubber helps protect the nosegear strut, and a spring protects the rear tiedown.
Even without these mods a Trigear is fairly capable off airport. My plane has done some pretty impressive things, even with me behind the yoke.
A limitation (IMHO) of a Trigear in the rocks is the nosewheel throws rocks at the soft underside of the fuselage and horizontal stabilizer. I've had to repair holes in both of mine. Not a disaster but a big PIA.
FWIW, the 182 is one of my favorite planes. I'd love a 300 HP 182, but who wouldn't?
