Is the coverage problem the backhaul to your WRT54G from the house  
LAN, or is it between the RV-AP and Client?

Is this WiFi card used for the backhaul?

Do you need this to be omni, or are you willing to aim it?

Again, 7 miles for the backhaul to an AP, right?  You'll need a  
directional antenna on at least one end of the link to get a  
reasonable link.
