Heh, i like the way you think. i kinda like that one...
Actually, the orange Tonka Dump and Doepke Unit Crane are probably next up on the block to start converting. The econoline cube Ambulance in there already has a thread started. I'd love to eventually do my dads 1962 America Lafrance AMF Wen-Mac Texaco fire truck, but don't want to mess it up.
Since you like crusty. Here's a Nylint stakebed i picked up to either just be a tow-truck load, or try to restore and build into a box truck (really want to build a 1930-60s Gillette razor delivery truck at some point)
