Recently bought a 2015 Unicorn Valencia S3 that we've just discovered has a leak near the entrance to the bathroom. This is directly under the roof join so we assume that's the culprit. Due to ill health the previous owners didn't use the van much for a period of time missing a couple of service/inspections. As such, there doesn't seem to be any warranty cover for this despite it being a known fault on the S3 around that time, and being well within its 6 year body shell integrity warranty. Reading other threads Bailey seem to have modified the design but does anyone have any idea what this is likely to cost us to repair? This is by far the newest caravan we've ever owned. We love the van and it still smells like new but this has us a little concerned/depressed about what we do now. Any advice appreciated.
