We have just taken delivery of a new Lunar Quatro 554 which boasts an excellent and large washroom. The shower is the biggest I have seen and has an eco setting on the showerhead so we will probably be using it more than on any other van we have had. However, when we got the van home last week we found a long strip of plastic lying on the floor of the shower compartment. I had a couple of adjustments made by the mobile engineer and asked him about this strip. He said it was to prevent water seeping out onto the carpet in the washroom and promptly clipped it back along the bottom edge. However, on closing the door it fell off again! He could not fix it in place permanently. I attended the dealers to have a look at a similar model and lo and behold, found a similar strip lying in the shower compartment! I enquired at the after sales office about this problem and another engineer told me that this was a common fault and "they all fall off, and there is no solution to the problem"! It appears then that this is a design problem from Lunar that needs addressing as a matter of urgency as we do not want wet carpets. Has anyone else encountered this problem and if so what have they done about it please?
