My suggestion,
An outside antenna hooked to a bridge, and that bridge hooked to a
wireless router inside your RV through the lan port. You might want to
not use encryption on your router, that way your neighbors will benefit
from your hotspot.

I like this idea simply because it offers more flexibility. The usb options
don't easily allow for connecting more than one computer very easily.
With a bridge and a directional antenna you can assure yourself that you
will always have a good strong signal however you could use it with an omni
directional antenna.
You could use a device that was designed to bridge or even one of the
linksys (wrt54gl) or buffalo (whr series) wireless routers flashed with
DD-WRT to establish a client bridge connection to the camp ground ap. You
would then feed from this using ethernet cable to a standard access
router/ap for you to do what you want with such as plug in additional
ethernet devices into the switch or use it wirelessly and encrypt.



A antenna, parts to connect that antenna to one router/bridge and an
additional router for local access and misc. cables and some configuring are
all that are required.

This is the way to go. There have been various discussions of this
solution and it's variations here before. A quick search for RV in
this group gives this long thread (your solution is in there)

http://groups.google.com/group/alt.i...&lnk=nl&hl=en&


Two big variables:
1) Put the antenna outside and the bridge inside - connect with low
loss cable to bridge. OR Put bridge outside in a sealed box with
antenna hooked up directly to it to avoid any antenna cable loss and
then run an ethernet cable to the inside.

2) Connect your various pcs to the bridge by ethernet cable, that is,
run cables around your RV and plugin wherever you are. OR Attach an
access point (cheap wireless router) to the ethernet cable and connect
wirelessly to your personal access point.

Drawback of the ethernet bridge vs the USB adapter solution mentioned
is that it takes a bit more attention to connect to the new hot spot
each time you arrive. But you only have to do this to the bridge, the
laptops will always be configured the same.
Advantage, as stated by another is that you don't need a USB client
adapter for each laptop.
