Hi VE, etc...
Slightly off your conversation - we just stayed at Seven Points in May.  Nice CG. Now drag a toad behind the B+, since we traded in the Roadtrek 4 years ago, so didn't have the issue you did.  Easy ride into Nashville from the COE. You might want to check out parking at Nissan Stadium.  LARGE parking lot, footpath/bridge right into downtown Nashville - supposedly free - plenty of room for the RT from what we could see.  Also large parking lot at Grand Old Opry - again no issue for RT.  Hope this helps!
