I believe your charger is already lithium. Just change the charge profile in your converter (it will be in the converter/charge manual). Truck charging (real charging) falls into Dc-Dc chargers and BIM. You can find plenty of discussions on that by searching. We have the BIM. There are also lots of generator discussions without a right answer - it depends what you want to do - run everything, charge batteries, etc. We use two Honda 2000’s in Parallel with a 6 gallon center feeder tank.
