I may be running it for a few hours so it would be a problem if I was slowly draining the 4Runner's battery.
Ideally I would have a small generator for this but it's not going to happen on short notice.

I doubt that you will be using all the 1000 watt constantly on a construction site, that is if you are using power tools (drills, saws, etc), they are used for a few minutes then the are off for a while. Thus, there will be no problem. Also, I doubt you will be using all the 1000 watts. Most power tools are far less than than that.
The car will not automatically rev up if the alternator cannot keep up with the load; you would have to do that manually which I doubt you want to do.
You might want to get a voltmeter and check the voltage from time to time. You can get some that plug into the cigarette lighter socket. If the voltage is constantly below 12 volts, the alternator is not keeping up.
