HI
We have a green coloured, they also do a grey coloured, Protec cover on our Bailey Senator Arizona. It has just gone for its 4th winter and is still in very good condition. It has got a couple of patches over small holes but that is because I failed to cover the sharp ends of the roof jointing strip the first winter I used it!! I subsequently gently rounded the rough ends of the jointing strip with a file and now cover the strip, TV aerial, front lights door catch, gas fire chimney and any other protrusions with foam pipe insulation, secured with elastic loops and duct tape. (The tape holds securely but pull off easily without damaging the GRP or aluminium panels.)
Protec provide 2 "free" extending poles for lifting the cover on, a hitch cover and a large piece of matching material for repair patches. We, also, bought the optional large storage bag, wheel covers and 2 storm straps (we keep our 'van in a rather exposed position). I have found Protec's customer service to be excellent. When the bag was quite new it tore near one of the handles and Protec quickly supplied a new bag with extra reinforcements in the area where the original had failed. On 2 occasions when I, carelessly, broke the plastic securing clips on the straps they have replaced these free-of-charge, next day delivery.
Protec have patterns for most well known makes of 'van so we just had to tell them the Make, Model and year when we ordered, no measuring by us was necessary. The cover fits extremely well, it has, extra material sown in to fit over the TV aerial and other protrusions on the roof. It has a opening door flap, secured with velcro, so that we have access to the 'van even when the cover is on. We have had no problems with damp, condesation or paint/window scratching from the cover and it keeps the 'van beautifully clean. As teachers we go away only during the school holiday periods and we put the cover on at all other times.
If you are a member of either the Caravan or Camping and Caravanning Club Protec will give a small discount on the price.
I have no connection or interest in Protec other than as a satisfied customer.
I hope this helps.
