Glad I don't have an AS, again (there are some things I really like). Drain valves on mine are in kitchen cabinet. Fresh water just off of tank and far from tires. Almost shielded. In the older versions, behind exterior access door. That said, the city water connection on one of the old ones was just in front of tires.
These companies did study each other. Frustrating that they didn't all use the best approach after one or the other introduced it. I could list differences and we'd all know the better one.
