Ok change of plan, parents have offered up some cash as our Xmas present, as we discussed getting Wifi and having it fitted.
So we have decided on having Maxview Roam fitted by a dealership (although not the one we are buying the caravan from). Which means drilling a hole in the roof

We have a choice of Struans or a dealer who Maxview suggest as an installer
Has anyone had this fitted and how does the 10 Year Ingress Warranty work by effectively piercing a hole in its shell? Slightly worried about this
