Skandik SWT, Expedition SE, or Bearcat Z1 XT - I am struggling with this purchase. I have found a a 2010 Skandik SWT V800 with low miles and a dealer demo 2013 Skandic SWT 600 Ace. There are many new Bearcats, 12' and 13' out there on steep promotions. No luck finding an Expedition. I've decided on four stroke only. Want deep snow capabilities, as I am alone most often, for shed hunting, scouting, trapping and towing firewood for the cabin. Also would like some decent trail characteristics when I travel to new areas or have friends or family up and they want to tour. Dependability is critical. High power is not, but I want to be able to pull respectable loads. The Yeti II chassis looks more work oriented to me. Is this correct? The V800 engine reliability seems questionable from what I read and the 600 ace looks under powered. The bearcat and expedition have large displacements, but the deep snow performance looks weak. Any guidance would be appreciated. This purchase is primarily prompted by an injury to my lower back and my old 1990's sleds riding positions are not cutting it anymore.
