ended up with three BP Solar 85 watt panels. Selecting the solar
panels depends on how much power will be used each day and how many amp-hours
of battery capacity is on board.
I used a worksheet on the web to estimate average watts
we would use each day. The salesman reviewed my calculations and
suggested three panels would be plenty. We installed the panels leaving
room to add a fourth later if required.

The placement and installation of the power equipment took weeks to determine the best fit. I learned a little more every time I talked with someone. Quite often I heard conflicting information and had to do more research to learn the real facts.
The panels are mounted using "L" shaped aluminum brackets and lag bolts. The panels are bolted to the mounting brackets. The lag bolts and edges of the bracket are covered with "Dicor" caulking to make a water tight seal.
The panels are wired together leaving some slack to tilt the panels. From there the wire was run down the refrigerator vent to the charge controller and then onto the batteries. The factory installed solar wiring was too small of a gauge wire and required drilling holes through the ceiling. I've heard that the wire is usually too small for all but a single panel.
An extension bar can be manually bolted onto one side to hold the panel at a tilt. This is useful to get the most power from the low winter sun.
"if you need to tilt your panels you don't have enough of them. "
