hello everyone - first question

having wanted a Merc based MH for ever, and been aware autosleepers make nice Motorhomes i am now finally here. having had 2 autotrails and a swift bolero i am now here at last.
So , first question concerns the onboard lpg tank - having never used one i will be honest and say i know almost nothing it aside from i know i need 3 euro fitment adapters for various parts of the eu.  

and, i assume a 4th for use in the uk ?  having looked online i see 10mm and 22mm fittings - is that something my side ? - ie do i have either a 10mm or 22mm fitting on my winchcome or is that something that changes abroad ?

once again - hello !

The pack of 3 European ones is all you need.
Welcome!!!

thank you !  but do i need 10m mm or 22mm adapters ?  is that particular to what size i have ?
