I did upgrade to a newer Mini 1000 and built a folding camping trailer ('TreNev'). A plywood box on a 7' 0" x 4' 6" angle-iron double bed frame (same width as the Mini) with shortened Lambretta front forks secured with 'U' bolts, suspension and wheels, lift up roof and canvas sides. 2 berths and gas ring. Bliss for the wife and I. Toured a few thousand miles with it. I've some 8mm cine film of it which I had transferred to VHS then CD but I can't seem to 'unlock' the CD to put it on public view as I don't have a 12 yr old now to show me.
