Yes , Bailey spares via their own stores PRIMA LEISURE easyily found on line
About £250 - £300 a set dependant on series .
If this is too high try contract carpetting from an independant carpet shop. Then use old carpets as templates ar cut in caravan to suit.,his cost us £70 for a 2 berth Pegasus Genoa,
If you go to the Bailey's shop or any caravan accessory shop you may be able to get a couple off runner carpets like what we have done and just run them down the centre of the floor for less than £2o , easy to take out and clean around and saves our brand new carpet getting marked and stained ( well of course we have got two kids ) but if you were actually wanting exact ones fitted you'd be looking at a bit more !
On every caravan we have had "ok only three" I have laid my own fitted carpets, no bits of mud grass etc , underneath. Vacum easily and when really dirty after two dogs , all year round, maybe after three years throw away and relay £80 a relay. .
You can buy directly from the company that makes the carpets for most caravans. I apologise but I have forgotten theri name a but a Google search should bring it up. Another good and cheaper source maybe a caravan breaker's yard.
