Got it

After about 2 months watching old caravan sales online, I took the plunge and won an eBay auction for £150. The van is a Swift Silhouette, estimated date 1989-1991, it's in a bit of a state.
It is about 12 foot by 6 foot, and reasonably solid, but has clearly been neglected for many years. There is a lot of water ingress around the front panel, with 3 fairly ugly windows - all seals dodgy. Some internal furniture has already been stripped out and there is no toilet. The floor, roof, back and side panels seem to be in quite good condition. The kitchen appliances are original and probably useless.
