If you don't need to move it, I might look at a Honda 3000. Quieter than a 2000 and a lot longer run time on a tank of fuel. We mounted it on the back bumper and it did well. I have also run the 2000s, both single and in parallel, and found them good for the job. I did set them up to run from a six gallon boat tank. If you need a longer run time, you might look at that kind of a setup. Of course, we were at the races in a field, so the generators ran for seven days straight, hence the longer run times needed.
