Thanks for the helpful comments folks, not to mention pushing me into yet another project, I've taken stock I have 2 duce and a half 1/72 scale trucks to try 20mm with. On the 28mm front I have 4 1/43 humvees, a UPS truck, 2 1/50 cars and 20 figures from the Westwind Roadkill line, Heresy trench coat gangers and assorted Hasselfree adventurers. I'll be doing this in 28mm.
