Inverter question

I to when started out on my first 5th wheel looked to power the entire rv on a mega inverter..but things just worked out differently than I had planned..most of my 5er was set up as 12v,lights,water pump,heat,Fantastic Fan for cooling,12v bedrm TV, so really what was the 110v for Livingrm TV and Sat.Box,and a few chargers for phones,laptops..The Micro,AC,Frig on 110,and water heat just draw way too many amps... So after doing reasearch I have a 5KW generator built in for running the Dual AC system to cool us off when its just too hot or micro wave, and both for lunch during mid day heat...for the TV and Sat.Box a 600w PSW inverter wired to a extra outlet by the livingrm tv for clean power and a 1500w MSW inverter wire to a outlet set into the steps going into the bedrm..using a extension cord for morning coffee maker and what might need some extra power when dry camping..now to charge the 4-6v batteries-shore power from the rv's 65amp converter, the generator powering the rv thus the converter and now the best invention- Solar Panels..which I have a 100w setup to just keep my batteries charged up when parked in storage and then the 2-250w panels for out camping at say at the race track watching nhra or nascar..everyones needs are different and then their setup will be different too.
