Ah. Cheers. Seems a bit exposed. I would have thought those sharp bits of metal sticking out would effect mot. Ankle slicers.
The plate underneatg the valves etc is to protect the plate from underneath. To the OP, the tank is under the van and doesn't actually stick out. If you are close enough to think you are going to slice someone's ankle you have already run them over!!!
It looks dangerous to me - I think a man (or woman, or gender neutral) should walk (or wheel or hop) in front of the van waving (or making another non aggressive hand gesture) a red (or other colour that offends no one and the colour blind can see) flag (or other totem).
I'm offended that you didn't finish your post properly. Waving a red what???? And don't you dare say "rag" because red waving flags offend my pet bull.
There is only a cover for the regulator. I have one on mine. They are available from a chap in America.
I'm now absolutely incensed that, having read your reply, (which incidentally didn't seem to contain an apology for your neglect) I have to scroll back to find the answer.
