Canine, I think so. When I was stationed at Ft Riley my company commander was a West Pointer hard charger, every time we had NBC training we went to the gas chamber usually annually. Yes you are correct it was horrible each and every time.
Welcome Lauren, you won't have problems with state parks or federal parks. IMO the state and federal parks are nicer than a lot of commercial parks, usually cheaper too. With privately owned parks it's a hit or miss thing. Some private parks have age limits on your rig.
