I know there was a thread on this in 2016 but wondered if anyone has been round since then. I've seen the filllpg app and notice that there's nothing on the north and west of the route. We are going late April/early May and have a single refillable 11kg tank and a 6kg Calor which we can change if there are Calor sellers on the route. So questions. Has anyone any experience of exchanging Calor bottles on the NC500? And how have people fared with gas usage? We've got plenty of time and expect to take 2 or three weeks.
