When I was in California, '89-92, saw an A-series at a show that had been bought new by a local plumbing supply place that had doors on BOTH sides. Can't remember if it was a 100 or a 108, but they had pics of it brand new with both sets of doors open, so it was definitely a factory deal. I believe a local carpet place had a couple of the A108 vans with no side doors for hauling carpet rolls...
