Hello All. This question shows my lack of knowledge about batteries and charging them. Thanks for the help. We just picked up our Reflection 260RD 5th wheel. When I'm not plugged into shore power, what is the better way to charge my house battery? I have a 2000watt champion generator and I have a NOCO Genuis 5 battery charger. Should I charge my battery straight from the generator or connect the battery to the NOC and then connect the NOCO to the generator? A second question, if I plug directly into the generator do I use a step down from 50 amp to 30 amp then to 20 amp, or is there a better way to connect the generator. Also, do I need to run the generator through a Power Surge unit before going into the RV? Thanks again for the help, John
