Another vote for a fixed installation. I would use nominally 12 volt panels with the Grape 40 amp solar charge controller from Home Depot.
Home depot periodically puts the Grape Solar panels on sale, with the last sale I saw being $85 a piece for the 100 watt panels. I currently have 10 of the 100 watt panels on the roof of my 5er, and had one that was only putting out about half power. Contacted Grape by e-mail and after a couple back and forth e-mails they responded to the same day, I had a replacement panel in my hands the same week. My experience is they stand by their products.
