The LPG filling at Gourdon was fine, made the mistake of driving into the Lidl car park to get some shopping first but the car park is really tight, the Carrefour one was much easier. As to having a twin bottle system we have never had a problem getting gas before & this time was just down to bad planning. We very rarely stay long in any one place so refilling is n't a problem. We can last about 2 weeks on the refillable bottle & we have a 6Kg calorlite as a backup (only ever needed it once). We only needed 9 litres of gas when we filled so with the calorlite we could have lasted the 2 weeks we will be in Sarlat. I would prefer having a bigger fuel tank rather than carrying extra gas. The tank is only 60 litres so range seems to be about 320-350 miles.
Nice free aire here as well so off for a hike into the town.
