RV er - I know what you mean about the small area on the roof - you have the same size unit as I have. I have read some conflicting comments on the size of inverter necessary to run microwaves. The part about watching TV using an inverter should not be a problem. The first steps I would take would be to have a sturdy shelf built for 2 coach batteries, install a couple 6 volt golf cart batteries, and install the easy fill tubing. These batteries by themselves should operate your TV for quite some time. As to the microwave, the generator (if you have one) should be exercised anyway. Fire it up and use your microwave those 10-15 minutes a day. :)
