Those older toaster oven models may use too many amps for your rig. Plus in small spaces those older models could heat the place up and even be something of a fire hazard. If you like toaster ovens, I would look at replacing it with a new one for reasons of safety and usage.
We outfitted our motorhome with plates, pots and pans from the local thrift store. Total cost was only $5. Often children of the deceased donate household goods to the thrift stores. Note: I avoid buying the small appliances at the thrif store because of the above mentioned safety issues. I always get new appliances.
