Is your 850 CCA battery your truck battery or is it a separate battery for the camper? That is not a deep cycle battery, if you have room for two 6 volts that would be best but one good 12 volt will probably be OK for you. I know there is not a lot of room on the roof so I would go with one 160 or 165 watt solar panel and two if you have the room.
