To answer my own questions.
The only electrical appliances that stay in my trailer are a small kettle, and a small cube heater. These are for the times I might be hooked to shore power and can save on propane use, plus the kettle is a bit faster than my outside stove, but not much, and the heater is quieter than the furnace. Neither one weighs very much.
I have brought a laptop a couple times and used the plug I have at the dinette to use it as a computer, TV or DVD player. Alternatively I can use a 300W inverter to use it.
One thing to note is that we do at least 75% of our cooking outside, using a Coleman 2 burner stove, the BBQ, or on a campfire.
In lieu of certain appliances I use at home, I employ the following;
-Toaster - I use the good old Coghlan's Camp Stove Toaster. It works great on the camp stove we bring along. LINK
-Coffee maker - First to be fair, I make coffee a few different ways at home, and none use a coffee maker (See THIS
thread for details). All methods can use the stoves.
-Coffee Grinder - I use a Porlex manual one. LINK
-Oven - I bring along a backpacking oven from Outback Oven. I like to make risen crust pizzas, cinnamon buns, and so on. And if lazy will just make up a packaged type cake. LINK
-Microwave - just don't feel I need one, at home it is mostly used for reheating things, and camping we tend to cook an appropriate amount that leaves no leftovers.
-We really don't use a lot of other electric appliances at home that are not replaced by propane ones in the trailer. WE have gotten rid of the electric fry pan, popcorn maker, food processor, quesadila maker, and a few others that saw limited use. My wife's Kitchenaide mixer might be the only exception, and elbow grease is used while camping.
As well, I am very comfortable surviving on multi-day trips into the backcountry using nothing but a single burner stove to sustain me.
