I just bought the 160W from Solar Blvd and have been pleased with it so far. Haven't gone camping, but did test it out in decent sun and was getting 6-7 amps.

When the panels come with the folding frame, bag, and other goodies, it just made sense. It comes with battery clamps, a male cigarette lighter adapter, and a 25ft. cord. The kit doesn't come with ring terminals for permanent mounting to a battery, so I'm going to try this out:
Battery Tender Ring Terminal Harness with Black Fused 2-Pin Quick Disconnect Plug - it hasn't arrived yet though.
Hooking a 12v battery directly to a solar panel is a good way to blow stuff up.
Mixing batteries is a bad idea. Older batteries tend to draw down newer batteries. If possible, you want to match size and age.
