Man I am liking where this is going. I have a 1997 Cummins that I just built a flatbed for last June and converted to run on WVO with a 2 tanks system. You are going to love the flatbed they are so handy. The only thing I miss is the ability to run a topper every now and then, but I'll address it down the road and it sounds like you have it covered with the canvas idea. With you now having 2 tanks and the Merc Diesel I'd consider WVO as a viable option, I assure you it works. If you want to discuss it at all PM me a phone # and I share what I have learned with you. Awesome project and my 1990 Toyota might have to steal some ideas someday!
