Some very sound advice JagManx.
We are not 'Full Timers' but we did take the decision to invest in a 'Gas-It' refillable bottle with external body-mounted filling point.
It cost ~£130 which inluded a discount as a Member of Wild camping Web Site (and a 'FREE' selection of useful Continental Adapters).
'Gas-It' will assist on the telephone with your requirements and perhaps more importantly after you have purchased.
All the kit arrives together, well packed and with a pretty fast turn-around.
And if you decide to go for the 'external body-mounted filling point', then once you get over the thought of boring a hole in the side of your prescious MH, it really is a piece of 'you know what', simples.
Long-term, it's a 'No Brainer' and no I'm not an employee of/friend of/or have any connection with 'Gas-It', I'm just a very grateful past Customer.
