After Sandy swept through NJ (about 2 weeks after we moved to Ohio) and a lot of our friends and family were left without power for a long time, the wife is full steam ahead on getting a generator. I have researched a fair amount but had some questions that I thought you all could weigh in on. First, is there any difference fuel efficiency wise or powere generation wise between a CARB Compliant model and a non-CARB compliant model of generator? I know I don't need a CARB compliant model living in Ohio but was just curious. Also, when using the generator, I would like to feel as little of the power outage as possible, more so for my toddler/infants so would like to have power to fridge, freezer, lights, tv/dvd, furnace/AC, laptops, etc. Currently have an electric range but would not be using that (have propane and grill/burner for cooking) or the microwave. Also, being military, we move a lot so I want to be able to take the genny with me. I've narrowed my serach down to two model. One has a 240 volt, 30 amp plug and the other has a 240 volt 30 amp and a 240 volt, 50 amp plug. Looking for your thoughts on the need for the 50 amp. I like the idea as bigger might turn out to be better at some point, but not sure. Prices are about the same, within $100 of each other. Thanks for the help.
