I usually build OOB with no extra detailing beyond paint/foil. This is my first (finished) attempt at something other than box stock. I used a '60 Chevy P/U, grafted the back half of a F350 dually onto the frame, planted a 348 W motor from a '62 Belair because I didn't think the 235-6 would be up to the job, and then added the camper from the Model King reissue of the Racer's Wedge/Camper. It was a lot of fun and has given me some confidence to try a couple other projects that have been lurking in the dark recesses. I especially enjoyed building a kitchen sink/stove/fridge as a change of pace!
Thanks for looking!
