Doing some research it appears that a DC - DC charger is needed between the truck alternator and camper battery to protect the alternator. Would this still be required with only one 100 AH battery? Truck is a 2006 GMC 2500HD. Also have 125w of solar.
Thanks,

hi Ralph it's awhile since I've visited RV.net. I'll tell you about what I'm using that does both solar and dc-dc in a single unit and I've been using for over a year. I'm going post a link to the story I wrote for Truck Camper Adventure. If you don't have a compressor refrigerator one Lithium battery (100ah) should do you fine.
