Hi I'm looking for a recommendation for heavy duty batteries for my 2018, 3500 Laramie Longhorn, 6.7 diesel, dually. I've gone through two sets of batteries over the last four years. I keep our Host cabover camper on year round and have only 20K miles. Sometimes it's 3-4 months between trips and though I start the truck up every few weeks my second set of batteries needs to be replaced. The camper is NOT connected to the electrical system on the truck. Thanks for any thoughts. Tom
