Adding an inverter to a Lexington 25.5

I have a 2007 Lexington 25.5 GTS. I am considering adding and true sign inverter as I have a Zamp 160 Watt portable solar panel. Any suggestions on an inverter type, how do I install, and what kind of drain I might expect from my battery pack? I have two AGM house batteries. We enjoyed Boondocking but my wife also enjoys washing and drying her hair each morning. This coupled with the ability to use the microwave would be nice. We have a generator but hate to run it when other people are in the area. Thank you in advance for any advice that can be offered.
