Thanks for your comments and suggestions.
I'll try to find a couple milk crates and will transport the tanks in a vertical position.
Filling the tanks I thought was "part of the deal". They said they don't have access to LP facilities. We're not done yet....
RVW had also quoted installing customer's hitch for $100 and is part of the written contract....until they found out it was a ProPride. (Told the salesman three of four times AND sent them the installation instructions!) They made arrangements for a local automotive shop to install the ProPride on a T&M Basis. As far as I'm concerned, I'm only going to pay the $100 that is part of the signed contract.
I'm sure RVW will modify their contract in the future to exclude the ProPride and Hensley hitches.
