I have an older champion 3500. Got it from Tractor Supply.
It will run my house air conditioning IF I shut off almost everything else. I did so during an extremely hot spell a couple of years ago.
Too heavy and too loud for camping. I bought mine for my home. If I ever buy another generator it will be a lighter inverter type for camping. I will not buy anything much over 70# so that will limit me more than desired capacity. Current generator is about 109# IIRC and too heavy for me to move around. Noisy as hell, too ;)
