The math is pretty simple. 10 amps at 120vAC is 1200 watts. A 2000watt inverter will do the job.
Where you run into trouble is that you're not really using 120vAC from shore power, your ultimate source is 12vDC. That means with volts divided by 10, amps is multiplied by 10 to get the same watts. Or to put it another way, for every 6 minutes you run the shop vac, you will drain 10 amps from your house batteries. Plan accordingly.
