I'll have a punt on it being early next year!!!
I have a confession to make !!
I found the reason for the problem of no lighting in the washroom,I did not realise that the pull cord for what I assumed was solely for switching off the vanity unit light in fact also isolated the overhead light !!****???. Suffice to say I came upon this little gem after purchasing spare bulbs and also picking the brains of the caravan sevice dept at my local dealer who left me no wiser , saying that I had better bring it in so they can look at it !! (imagine my embarrassment if they had realised what I had done )
Ah Well !! at least I have learnt my first caravan lesson.. ... ... ... ... ... ... ..READ THE B++++Y HANDBOOK PROPERLY !!.
Thanks for all the replies (at least the clear polythene has gone now and I have light in the washroom ).
Ohh Heck, sounds like another month of trawling through new caravans next year then!!!!
Then I also have the problem, do I keep the van I have now, which I have gone through and fixed all the issues on, effectively doing Baileys PDI for them, or do I get a new van and start all over again??
