That's fantastic! I've been wondering how I could do something similar! If I could get the body on a trailer, I could store it for a month or two while I fix up the frame, and have full use of the garage... AND I could also use a DIY shop's lift for $50 when I'm ready to undo the process. Personally, $50 is a way better deal than 2+ hours of hard labor.
How did you secure the body to the snowmobile trailer for transit?
