Use two 5 watt solar panels and a continuous duty isolator relay. It

can't
get any simpler than that.

Okay sounds good. The isolator would connect to what other than the
two batteries? And it's purpose would be to keep anything on the boat
from pulling from the aux right? Also, would 5watts overcharge the
batteries and require a controller?

Yes, the batteries would have no load while sitting, but I'm recalling
those two week trips and my car not starting when I got back.

Thanks!

The relay would be turned on by the ignition switch. You could add an
isolator relay delay and make the installation a little more

sophisticated.
Don't worry about overcharging. Look at the Intellitec web site for

details
on the products I mentioned, and others.

What you want is a battery combiner not an isolator. $80 at West Marine.
When one battery goes above 13.4V (charging) the relay combines the 2
batteries. Less voltage drop than an isolator.
