I would NEVER attempt to pull into the Camping World with my rig - and I have taken it into others around the country. The Tucson location is terrible for access and there is NO parking. Hard to find a place to park a car sometimes. The little space available is usually taken up with with rigs for sale. When we were there a week ago my sister-in-law had a hard time navigating the lot in a car - had to back up twice because of other vehicles and no room to pass each other.
That said the service at the parts counter was excellent!
