Not Oshkosh specific, but body color, black or a medium dark grey would be my choice based on most trucks I've seen. Body color seems to be more common on higher end stuff where they don't mind paying a little extra to make things prettier.
Aaron,
Thanks for your reply. I am in the process of painting the chassis components like the axles, springs, etc. Busy at work at the moment. I will update the build thread soon.
Hey bud. Could you give me some detailed dimensions on the cab and stuff? I want to build one in 1:24 scale since no one sells much military in this scale. Thanks.
JT,
I don't have a 1/35 scale ruler to convert the measurements for you. I WISH that someone made a 1/24-1/25 scale kit of the M978! One modeler built a large scale R/C version that is easily found on the Internet. You may want to pick up a 1/35 scale kit to use as a master to get your shapes and measurement conversions. Good luck.
David
