Bailey Motorhomes- Gas Bottles

I note that the Bailey Approach can take 1X6kgs and 1X13 kgs gas bottles. Has anyone tried using a 10kgs BP Gas Light and a 6kgs Calor Lite? I appreciate that they need different pigtails. We usually carry two 6kgs Calor Lites but a few days ago we were staying at the Camper Stop in Fussen and had to use gas as the cost of the electrics was going to bankrupt me!!! I don't particularly want to go down the refillable route as I suspect we would not see a return on the investment.
