Thanks everyone. Deadsfo, it's in almost daily use and we've spent a week in it back in October without heating or cooking etc. and we loved it, so as long as it behaves mechanically we should be ok! It's had a new stainless exhaust this morning and I'm going to service it tomorrow. Noticed the bushes on the gear linkages aren't great too, so I'll do that. It's just a matter of keeping on top of things. Might be worth you checking the linkage on yours too, I lost third in wales! They're 50p each from Merc and it's an easy, if fiddly, fix. I stupidly only did the one, so I've got to do,the rest now!
