Refillable gas options

Hi folks,
I'm new to here and new to motor homes. My wife and I just bought an old Hymer 1990 B644 which has German gas bottles and regulator still on board. We will be touring Europe for 6 months from September.
We would really appreciate any advice from experienced users of refillable gas systems such as Gaslow cylinders. Also if I wanted to change the regulator to fit regular Irish cylinder can I just use a household one with the orange flexible piping or does it need to have special pigtail? (As a temporary fix so we're not gas-less when the German cylinder runs out). Thanks.

Using Gaslow for seven or eight years - works like a dream. A little expensive to buy and install but you can take it with you to your new motorhome if you change motorhomes.

Gas bottles are a nightmare with no standardisation of in one country never-mind standardisation across European countries. The refillable cylinders that use Autogas (like Gaslow and others) get over all that nonsense.

The other factor is convenience of not having to lift out those cylinders and hefting up a full cylcinder into those little gas lockers every time you use a bottle of gas. Just pull up to a petrol station that sells autogas and top up - easy as filling up with diesel.
