hi pc,well it is the galvanised chasis,all panels are perfect windowes etc no problem,all electrics work 12v and mains,we had our first trip a cple of weeks ago it was great we are going away again next month,the only issue is: it previously had a bit of damp in the rear top corner it does not rain in it has been repaid with some kind of sealent on the roof corner,it has had new panels fitted on the inside and wallpaperd,however on that side the grab handle on the outside moves with the exterior panel the otherside is solid,i am going to buy the caravan manual from halfords,then after our next trip i intend to strip the inside in that area as it may need the timber renewing,so any advice would be nice,steve
