Gas options during shortages; refillable vs swaps

Hi all - I’m currently in the throws of my campervan conversion and trying to sort out my gas. I had a location sorted where I planned to just use a calor gas bottle, but I’ve been calling around and am being told - as most people probably know on here - that there’s a shortage. So this has got my back to the drawing board and I’ve discovered the refillable option from Gaslow and I was hoping for some input from folks whether this is a good option for me in light of the shortage. I’m not living in the van, and would only be doing a combination of day trips, some uk holidays and over to europe for a max of 2 weeks at a time, never in winter. Only have a hob, and not hot water/shower and fridge is electric only. We’d also be using hook up quite a bit.

The refillable Gaslow option isn’t cheap initially, and a ballache for me to install at this point, but seemingly it does allow me to fill up in europe and gets me out of the bind of the calor gas (and flogas) shortage. It also means I can get away with 1 bottle (with refillables my plan was to have 2 bottles so I could have one-on, one-off, which seems less of an issue if I can just refill to the top again rather than sacrifice a bottle even if there’s a bit left).

But do folks think a whole refillable system with a hole in the side of my van is overkill just for a hob, and if there’s an easier way to get my hands on a refillable bottle? (However I’ve been told by the folks I called that even if I bring in a bottle there’s no guarantee they’ll be able to swap it at the moment as even the swap bottles are in short supply) Thanks!
