Leaky "very expensive" fifth wheel caravan

Hi Guys,

My first post on here so il try to keep to the rules but please give me the heads up if I stray!!

OK so I'm looking for advise as to what to do (if anything) about a leaking caravan less then 3 years old.. I purchased a Fithwheel co Dreamseeker caravan in March 2019 direct from the manufacturer, it was 2 years old then so just less then 3 years old now.I paid £56k..

As the caravan was used I only had a 3 month warrantee. It was fully serviced by them just before collecting.

Not long after and within the 3 month warrantee timeframe I noticed that there was water getting into the slide out, I contacted the manufacturer to discus this with them by phone and they explained that the problem would most likely be that when siting and levelling up the unit I need to insure there is a slight drop in level towards the slide out, this they explained was to insure a good seal and encourage rain water to flow away from the seal.. This made sense to me as I was not aware of this. over the corse of the summer every time we used the caravan I experimented with this and found that the issue was not fixed by the leaning.. I then came to the conclusion that it was in fact leaking from the roof in the slide out, I have had a caravan engineer take a visual look and it seams that there are 2 very narrow beads of silicon that have failed and that is the most likely point of entry however without further investigation it is hard to confirm. 

So now of course I am way out of my warrantee so I contacted the fith wheel company to ask if they gave a water ingress warrantee with there units, they advised me that they do and its for a 5 year period, however as the previous owner I am told missed his first service it is no longer valid so they will not cover it or even investigate it without a charge!!

Now I'm aware that as far as the black and white small print goes it seams I'm not in a legal position to insist they make the repair but from a moral point of view I see it like this:

I have probably the most expensive caravan that money can buy built by a company that states "we are the Bently of caravans" in there advertisements, yet its less then 3 years old and water is gushing in through the roof and because they misled me while I was within my warrantee period that the issue was down to me and because it missed a service 2 years ago there not interested in helping out in any way!!

I suppose what I'm after here is any advice but also peoples opinion, am I being a nightmare customer and should except that I have no grounds to argue and just take the hit or am I well within my rights to be upset and let down??

Thanks in advance guys
