Irongoat, I dunno...
I rather like the four door Wert provided the link to at the Ritchie Brothers auction. It's not nearly as nice as the Aleyeska Tuckers, but the front blade is a major plus and so is the four door cab.
I looked at the photos pretty closely. It's newer than the two Tuckers I've had with front blades, but the mounting is completely different. I wonder if the blade was added later? The "housing" underneath the blades T-handle control doesn't look like Tucker, and I doubt they would hack up the square mesh (left side, front) to run hydraulic lines either.
Sometimes Tuckers go cheap at those auctions and perhaps that will sell for under $10K. But then again, there's probably a lot more interest in snow cats this time of year...
