building a network for my RV

I am trying to create a Wifi Network for my RV.

I have a Wifi AP/Router in my RV appropriately secured and all my client devices attatch to it no problem.

I need to give my network a WWW gateway, the Campsites whe visit have WiFi, in some cases WEP in other not secure.

so my goal here is to have my little private network kept private, while somehow connecting a device to their Wifi to provide a NAT gateway.

The question of cource is how?
I messed around with DD-wrt and the forums there are well, useless.
only answer I got was "repeater" and a few other words that amounted to 'go away' So I plugged away with the DD-WRT for 5 or 6 hours and its far too clumbsey for a mid level user. All the changes needed to change campgrounds every time would end up not worth it as I dont feel like spending all that time on this every weekend.
I am now looking at UBNT NanoStation Loco as a soulution. anyone know if this will work, oh and I think client bridge is what I want, anyone able to clear that up?

Thanx for any help offered!!!

been there done that:

you have to log in to the bridge and configure the bridge to connect to the local internet connection
