We are still awaiting confirmation on our roof.. 'Devon' or Danbury I've not got access to it yet to take pics but I'm just wondering how easy it is to get new struts pref hydraulic ones... Ours are cream crackered! Also which are the best bunks to fit as ours came with some but they are so heavy and massive ?!
Really hard to advise without good pics of what you've got, 're bunks, a few have converted to a proper double bed set up up top, I'll try and remember who it was did a how to thread on it.
There is one on eBay actually for a Devon...just not sure as on pics I don't think it looks that strong?!
