Hey guys I am trying to figure out how to make a dumpbed for my old dodge. It is a 1977 custom 200 longbed that I am redoing for my 16th birthday. I am having it painted right now it will be green and black the trailer will be getting a coat and signs. I was wondering how I could do this I want to do it on my own because I have all the tools. Which would be better A hydralic hooked up to my pto through my transfer case which is a np 203 with a pto option. Or should a electric powered pump? A airbag type with a compressor on board. Please post all of your thoughts and ways to do this.
