We've just purchased an old beast of a motorhome that runs on propane (LPG) which is very easy to get a hold of here in Canada but we've heard that it's not as easy to get in the US. We are planning to go to the Oregon Coast on a trip next week (through Washington state) and have been trying to find a comprehensive list of propane retailers online. Does anyone know of any great resources to help us map out our trip to make sure that we don't end up "camping" by the side of the road? Or does anyone have any other words of wisdom about travelling in the states with a propane engine? Thanks!
