Welcome Jonathan, We'd love some pictures sometime of yours too!
i'm with Campton personally though for no particular reason as there's a choice now, I suppose if all fails you could insure camper on truck with one of those on forum and have camper on home insurance when not in use.
Certainly been commented on that insurers can be a bit spiky over offering cover where someone wants to use truck for both work & play
but that might not be relevant in your case
