I have a red coloured 11kg Calor Gas (propane)full gas bottle, weight 23kg, it is not suitable for my van but I am told it would be OK for a ROI motorhome as it has the correct screw connection. As I am not sure of suitability,guidance would be appreciated . I will be heading down South this Friday to Dublin so an RV at Apple Green services would suit if I have a buyer. Price 20 Euro.
