Hello all, having a great time in our first MH a 2009 Terrestra 570 HS, and thinking of boosting the electrics a bit so we can tour round europe off grid more readily this summer. The van is as per the original spec with two 105ah LA batteries and I'm thinking of converting to Lithium as a starter. Anybody done similar with one of these vans? I'd appreciate advice on the B2B and inverter to use if I drop in two 105ah lithium batteries (Fogstar).
