I won’t pay much more than €25 about £23 at current rate, we carry 2 bottles which usually get us back to France or Italy, Campingaz is a rip-off as quite often for smaller campers it’s a captive market, was in NL Sept and was asked €35 I gave them my opinion on that.
To save € if we can cook out we use a compact single burner that takes the aerosol type can, Action stores in Netherlands, Belgium & Italy about €1.20/can they are also a ripoff from Campingaz at €3.50.
Campingaz 907 € 25.00 = € 9.10/kg
Action aerosol € 1.20 = € 5.55/kg
The aerosol is still not cheap but as it’s not possible to fit a propane tank to a Cali there’s not much of an option unless you ditch the spare wheel. Although I saw a tank from a T3 Westi Under a T4 Cali, even with high suspension there’s not much ground clearance, not much good for many on here with dropped suspension and elastic band tires, ground effect comes to mind.
