Abbey and Swift sides are the same sandwitch construction. Swift's outer layer is aluminium , Abbey's is GPR. If you damage an aluminium panel a new sheet of aluminium can be bonded over by you're local workshop, if you damage GPR your caravan has to go back to the factory for a new side, expect a 9 month wait. Patched repairs of GPR sides are unsatisfactory. 2001/02 seems to have been a bad year of manufacture for Abbey sides. Like all things, once you find yourself in trouble with a product suddenly your not alone. To be fair after a lot of hassle and loss of use of caravans Swift group has sorted people out under warranty, what happens after this runs out? Now after a few teathing troubles I am the happy owner of a Swift and I wish the best of luck and that nothing happens to Abbey owners.
