I went to the Stafford MH show Saturday hoping to get advice, but no one there was selling them. We have an old van with no outside gas point, but are thinking of getting one fitted if possible later this year. We don't want to lift the gas bottles in and out so would need to use the small canisters for the time being. Do I need to get a hose and regulator? Are the canisters propane or butane? Would like to order one off Amazon, but need to know what I am doing first.
