I don't know that I'm the right one to ask. Really it's the end-users who are going to be able to tell you that. From the information I know of, it does work.
Again, our members aren't the ones installing these. However, that may be changing somewhat, because, for instance, General Motors has an engine that is a marvellous natural gas engine, but it is not expert in the fuel system, be it liquid or compressed natural gas. But it does have the engine that can handle it. It would like to see an intermediate manufacturer installing that, and that falls under the realm of the multi-stage manufacturing process that all of our vocational equipment is manufactured under and recognized by Transport Canada.
That's what CTA is kind of all about, that multi-stage, because with a vocational truck you get a chassis from the OEM and then the next manufacturer may be installing a crane. They are affecting regulations. I won't get into the details, but they are.
