Our van is only 4 months old and the shower wall against exterior wall de-laminated the other day. Van was sitting in same place and OK for two days, then 3rd day - wow, most of the wall has come away. Only the toilet and where the plumbing is fitted is holding it on. In the cool of the evening, it appears to "stick" back on - have they used a heat sensitive adhesive?
It will simply go onto the growing warranty list.
Does not stop us using the shower, we are not worried as it will be fixed, so we are just going to enjoy the rest of our Bridport foreshore holiday - only 30m to the shore for the kids, plenty of beach cricket, 100m to the rocks for me to fish everyday and a fridge full of chilled wine, beer & food.
Happy Holidays
