Solar Panel options

Hi people,
I am looking for a solution that will allow the following.

When taking our caravan to

1) Charge our 12v deepcycle caravan.

When going camping with our tent only

2) Charge our mobile phones and PDA devices and rechargable batteries.

Does anyone know of a solution that will allow me to purchase some portable solar panels allowing me to do such?

I dont not mind if I have to purchase extra perihipals to accomplish such a task, but before I fork out some jard earned cash want to make sure I purchase the right solar panels that will allow me to do such.

Thanks.
