I can't help you with the SVO conversion since I make biodiesel, but maybe someone who can help will chime in. Do you have a WVO source confirmed? I've seen this as the biggest obstacle for most people. It would be a shame if you went to the trouble of converting your truck only to find you are unable to secure oil. If you're really serious about going forward with the conversion, you might as well start knocking on some doors, making contacts, establish relationships, and start setting up a collection system and agreements. It sounds like with the right guidance, you're the type of person who has the ability to get the conversion done. So while you're doing that, you might as well start building up your oil supply.
