3: inverter is 400watt a little big I know but I will have it tied into an auto start generator so I can run air conditioning if needed

4: as for charging I will be living off grid full time with verry minimal shore power, unknown how much driving I will be doing so can't say how much alternator will play into charging I do have a 5000w generator that I would like to run minimally if possible

5: as for fitting the solar panels on the roof it is a 36ft class A motor home and I have just enough roof room to fit 8 panels flat mounted
