Power Inverter

Hey guys/girls I am looking for some advice on what converter I should run. I would rather have much more than I need then not enough.

I would like to run fridge (all the time), LCD with DVD, laptop, rice cooker, microwave, skillet, and a slow cooker. Obviously not all at once, but fridge, and maybe a couple others at any given time. LCD for movies when I am not using the laptop. Cooking stuff would only be used for meals, or maybe the slow cooker/rice cooker would be on extended time.

Any help on this would be great. In addition do large companies that allow stuff installed in their trucks usually have a limit to inverter size etc... I was told whatever I get and want installed into their trucks they will do at their shop for me so its done correctly.

 

Do most power interters show you how much of its power you are using? So you know how much you are loading it up.
