Victron energy sells the Orian line that is battery to battery. I have one that is 18 amp output and still get by useing the 7 way RV flat cord. Any thing more then 18 amp out put you really need to have a Andersen connector for the truck side power. The Victron is compatible with any current battery charge profile and is current limiting for Lithium battery's. It programs with the use of any smart phone and there down loadable APP. I Like Victron products for a few reason they are very efficient and don't generator a lot of heat . I have mine set up to turn on with the parking lights and charge so If my solar is running the truck charge isnt needed. The 18 amps is enough of a charge rate that it keeps up with my inverter and residential frig running.
