Welcome to this forum Matt!, first my condolences on the loss of your father, I sure he is looking fondly over your shoulder as you roll his truck down the road, and probably giggling a bit as you struggle with dealing with the scale house LEO's.
May i kindly suggest that you spend a few nights on a different forum. the Escapees HDT I tend to hang out on both, this and that. but The Escapees is full of very helpful guys that have done exactly what you are proposing to do. Just copy/paste your same question there and whach those guys come out of the wood work to help you. But you have to post here with your progress as we tend to be more build it yourself kind of guys here, hense the name.
Good luck with your build. Mine is detailed on the MDT forum on Escapees also.
