Folks- we are picking up our Oliver in February and it will have the new lithium batteries. We will be towing it with a 2021 Ram 1500 5.7l hemi with etorque. As best as I can tell from the folks at Oliver, the Oliver Lithium system wIll not be charged by the tow vehicle electrical system, but it seems that it could be. Anyone know anything about this? We previously owned a Roadtrek class b with lithium and a second alternator kept the lithium batteries charged very nicely.
