Because my 80 is not a DD I wanted shore power for my batteries. I have found keeping batteries fully charge gives them much longer life and what better than solar. I have used the Solar Battery Minder set for several years with excellent results. I mounted the panel on top of the covered area where the 80 rest and mounted the controller high up but easy to see. I wanted an obvious connection point so I did not drive off plugged in. I mounted the SAE connector so it is easy to plug in and hard to miss when I go to leave. If I plug it in with fully charged batteries it will keep all 180AH charged.
