Do I need a Generator?

I got a Ryobi 2200 at Home Depot last year because I wanted power at the camper storage lot, as a bonus it will also power my gas furnace and fridge (not at the same time) at home in the event of an extended power outage. Have not tried, but I seriously doubt it could start my AC in the camper, but it will run everything else (your results may vary). The one time I could have used it camping - we forgot it at home! Oopsy! So, the do you need it question is very personal and there are also other options already mentioned.
