I just built my first chuck box out of 1/2" MDO and used two coats of Sherwin Williams All Surface Enamel as recommended by the paint store. The paint was a disaster. It didn't coat well and after two months of curing, still has a sticky feeling to it. I am reasonably happy with the chuck box as it stays in my pickup under my tonneau cover at all times. It is 26" wide, 18" high, 18" deep. It is heavy at 40lbs empty but this is for grilling on the beach, tailgating, and park and base/camp with my kids (Cub Scout, Girl Scout, Boy Scout). I did treat myself to a 5 pound LP Tank instead of the green 1 pound disposable or lugging my 20 pound. You can still see some sand from our least beach trip.
