In your year it was an option, not a feature, so could go either way. The brochure lists a 300amp as standard (battery charger basically) but an optional 1500amp with remote display that would supply some amount of 120v power to the outlets. Do you have a control panel for it in your One Place utilities panel? Probably labeled "Dimensions" with buttons for "display" "Inverter" etc located near your air conditioner control, tank display etc.
Another way to check (and a good reference) is to go here...
http://dealer.winnebagoind.com/unitsearch/parts.htm
click on your year and add the last digits of your RV's Winnebago serial # (not the VIN) and you'll get a web page with the complete parts list for your specific build. You can then search the web page for "inverter" and see what it shows.
