Portable Generators

Depends entirely on how many of those things you plan to run at once, obviously. To figure it out, you need to add up the wattage of those bits. You need both the "running wattage" and the "starting wattage", aka "surge wattage." Things like light bulbs, microwaves, computers, the running wattage and the startup wattage are pretty much the same. Things that have a motor, however, the starting wattage is typically 2-3 times as much as the running wattage.

I'm sorry my friend, but you are gonna have to do the math. Any recommendation without it is just a guess. Add up both the running watts and the surge watts (separately) of everything you want to run at once, add a bit for a safety factor, and you will have your answer. Don't forget about the TT's converter, which is going to need room to be able to recharge the house batteries.

Now for a BIG guess: you do want to run the AC with some of the other stuff. Most folks find that JUST the AC and the converter recharging batteries can be done with a 3,000 watt generator. The limiting factor being the surge draw of the AC. The central question is how much OTHER stuff you plan to run at the same time.
