The gas
During our trip we saw that the exchange of propane bottle was going to be complicated. You must take a subscription in the country where you have it, return the bottles to the corresponding country ... So we found an alternative and much less expensive solution.
If we can think that switching to LPG is expensive, in fact in France they make you buy special bottles (400 euros one). But however you can very well keep your 13kg propane cylinders and fill them up to 21 L. (Remember to empty them completely to put the right liters.) The purchase of the filling kit is very easy and quick. A filter can be added to the bottle because the LPG is not very clean. it costs around 50 euros.
