The Sharp R-55TS
is a combo microwave and toaster oven. We wouldn't use it until the next time we camp with full hookup so I've been watching for sales and/or rebates. I thought was covered in a past thread but maybe that was on RV.net Lots of microwave/convection combos out there. Convection is great. We have a convection oven at home and love it. But, for quick food in small portions the toaster or microwave seem more useful. If we've got time to bake a regular meal the regular oven in the Argosy does the job quite well.
Did find searching the old treads that some units have an AC/Microwave switch. Because of the power a microwave or toaster oven can draw it only lets you run one at a time. I'll just remind myself not to do that... er, just like I never run the microwave and dishwasher at the same time at home
