Having attended several nascar races, having a quiet gen is considerate, but it seems there is always someone with a oversized construction generator that they want to run 24/7.
Like many posts on many forums "just do what I do". LOL
We have 2 Honda 2000's with a parallel kit and an IPI Industries long run kit. The smaller Honda's are easier to move around and load and unload from the truck. Pus if you just want to charge batteries or run a fan you can run just one.
The Honda's are pricey. I would also consider Smarter Tools, Champion, or Generac 2,000 Watt inverters with parallel and long run kits.
