Also a few years ago there was a forum member (Swampcruiser?) who had taken a mid-1960's Chevy van body and used that along with taking a section out of the Tucker frame. It looked pretty darn cool and was very functional for his family.
Here's a link to the Tucker van conversion I mentioned. We've all seen snowcats that have different bodies on them. Some look good and others...well, not so much. I liked the look and the proportions of this one. It's too bad Swamp Cruizer is MIA from the forum.

Had a Chrysler 440 big block that used 8 gallons/hr when grooming!
I like the design where the blade pivots from the front axle. This eliminates the force going threw the fifth wheel pivot points and the forces going from the axle threw the springs, shackles and spring bolts too. Seems like the front axle is doing at least half of the pushing to the blade. $. 02.
