Can you fit a refillable gas system to your motorhome for under £200?

I installed a Gaslow 11kg refillable bottle to my motorhome and a remote filler point on the exterior for under £200. 11kg bottle was £130 , remote filling kit was £49.99 and calor adapter was £19.99. All bought from eBay. Only extra tool I needed was a 70mm hole saw that I borrowed. The fitting was straight forward enough and there were no surprises. I have since gone to the service station and filled the tank, it took 21.06 litres and the gas appliances are all working fine and no leaks. The 6kg bottle takes 12 litres and cost £25 to swap out so at todays rate would cost me £9.58 at the pump, should work out to be quite a saving over time not to mention the convenience.
