Thanks for all the comments on the build. The pintle is from PMD and I think it's a good product. May have to install a spring to keep the lock closed.. Never thought about the edge looking like a plasma cut but it does. Tried a lot of different methods for cutting styrene and ended up using the band saw with 18 tooth blade. It cut the fastest and left that edge. I'll do up a drawing for the switch and post it later.
Back on the dump box. After it was finished I gave it a coat of Modelmaster Chrome silver and made the overflow boards for some mahogany.
In this photo you can see the servo for the tail gate latch.
I also had to shorten up the cab floor. I worked it out and was able to fit in the 12 volt battery for the dump. Two esc's are for truck drive and dump
Next up will be painting the cab.
Thanks for looking
Rob
