My favorite multi function cooking appliance.

Thanks for all the responses. This post was at the request of my wife to see if we were missing anything. 

Our problem is that we don't have too much extra space in the trailer or t.v. and we don't hang around the trailer very much, so we come in tired and hungry and just want to eat and wash the dishes. Simple and compact appliances have their attractiveness to us. 

Instant pots, camp chef cookers or GMC ones seem to be too bulky for their usefulness, but as was pointed out, this depends on the menu that each party prefers. 

Our electric fry pan and the microwave/convection oven meets almost all of our needs but one thing that comes out of this is, I do think I have not taken sufficient advantage of propane grills so I think we'll get a small Weber and see how it works out.

Unfortunately, there is no one "do it all" appliance. The best thing is to find the appliances that can meet your needs for the various types of cooking you need to do. For example, we have a Coleman Grill-stove which has a single camp stove type burner and then about 2/3 of the space is taken up with a grill (great for burgers, steaks, etc.). Separately purchased for that is the griddle that takes the place of the grill. That is great for bacon, eggs, pancakes, toast (regular or French), etc. However, one would be hard pressed to cook other things with it.

Next is a good cookware set. We have the ten piece Magma nesting cookware set that is induction capable. I like that there is a variety of pot sizes and a frying pan that all nest together along with handles that lock in place so they don't fall off if one inverts a pot. These may seem expensive, but the quality is as good as any high-end cookware set like you would get for your home. They are available in non-induction also. They can be used on any type of stove to include induction. To go with that is an induction cooktop. We bought ours at Aldi but Amazon carries a number of models from $24.99 and  up.

An electric pressure cooker (AKA Instant Pot) is good. These are very versatile and can be used to sauté, steam, slow-cook, or pressure cook. One can cook rice quickly, including brown rice. One can even cook cheesecakes in them (with the proper pan, that is).Soups and stews? no problem. The down side to these (and induction cooktops) is that they need shore power or a good generator to run them.

Well, that is enough for now. You will figure out what works best for you, your style of cooking, and the space available to store things.
