Hi coola Regal furnishings took £450.. Drove in at 7 am they measured up and listened to what I wanted ie high back on rear facing to fit the bed etc then chose fabric and went back to bed for a couple of hours while they made them up. Was done and away for 12pm. Great job. Foam is 5 inches only with a choice of firm and hard. Firm is really comfortable both as seat and bed and showing no signs of wear after 1.5 years constant use
They're in Ilkiston Derbyshire took me about 6 hours from alans in Cornwall. They are also happy to let you stop the night in their yard and provide free power and a cup of tea in the morning. Alan says they posted his to him although he knew exactly what measurements he wanted. mine was a bit more difficult to judge as i wanted the curved edge on the small seat and the split in the big seat back for the bed.
Well best drive about the uk to check its reliable before you go away long distance not had mine waxoiled yet always been too wet in scotland and its a bit wet here in portugal too
