I am thinking about buying a Diesel 1993 Ford E35O Mini School Bus and my plan is to convert to svo. Is this possible on this particular model? What vehicles are best to convert? Does anyone know around how much I'm looking at spending if I want to filter onboard and... I'm assuming I need 2 tanks? I'd love for my next vehicle to run on svo but I know nothing about how to do it nor who to speak to about it, so any information is super appreciated! Please help!!!
