I just noticed the title or whatever you call it for swinada, it says crew member. what is that?
I guess you have to ask Steve about that. I guess this changes automaticly probably according to how long you have been a member of the forum and how often you post.
Mine changed when I offered to help clean up the tutorials and work on the wiki a little. Unfortunately I have been slacking thanks to deer season, but I will get on it now.
Oh yeah...CNG motors. I don't see why it couldn't be retroed to work on propane if CNG fueling is an issue (and it is). As for recertifying the tanks...I do believe it is just a visual inspection done by an appropriate shop. The local propane place does it I know. It can't be THAT expensive, certainly cheaper than the new tank prices you quoted.
My utility company gave me the name of a shop that's not to far. They told me CNG tanks have to recertified every 36 months. When they reach their exp. date, that's it! They're toast. I kinda figured that when I bought the bus. It sure is a sweet ride. Now I just have to find a motor.
