Can I run a fan with a 3000 watt inverter in my camper?

Yes you can run a fan. You would be better off using a 12volt fan though. Why invert 12volts to 110 volts to run a 110volt fan when you can have a 12volt fan and skip the middle stuff.

I'm having trouble understanding what you are trying to accomplish or what your ultimate goal is. Are you simply trying to boondock for a few days or are you aiming at a full "off-grid" system on a more permanent basis?

If you are considering a full on, self sustaining system, a simple power inverter isn't the answer. For prolonged living off-grid you should consider several solar arrays and a large battery bank. Optimize your entire RV by converting as much as possible to draw as little as possible. Instead of 20 or 30# propane tanks, get a couple of 100# tanks. Get rid of your RV toilet and get a composting toilet.

If you just want to boondock for a few days to a week, forget about using AC or microwaves. A simple marine battery will run your 12volt system and a small solar panel will maintain it's charge.

Eliminate 110volt things like the boom-box and coffee maker. Car/RV stereos are 12v. Make coffee on the stove top.

There is a wealth of knowledge, experience, and videos on youtube surrounding both short term boondocking and all out "off-grid" living. In the end, inverters are not the best answer no matter if it's a small 200watt or a 3000watt. How many watts you can invert for your appliances means nothing unless you have a battery bank to back it up...and solar, wind, or turbine power to continually charge the batteries.
