What can I do with/expect from a generator?

We have boondocked four days easily without, but for skiing this winter and possibly up to one week of boondocking... Saw a used Honda 3000ec available for $750. What will that do for us? How long do I need to run something like that the charge our batteries up? I have two 6v batteries.

Look at the bigger picture, your profile says you have a travel trailer, how many gals of FW does your tank hold? If it is 50 gals or less that will be your limiting factor especially if you have not dry camped before with your wife. A Buddy heater as Bud suggested uses no battery power and will heat a small trailer. With two 6 V GC batteries with lights, water pump, refer on propane mine will last 7 days before they reach 50% SOC and with 60 gals of FW my water tank will be empty. I don't know what other electrical requirement you have. If you take showers every day you will probably use your water up in 5 days or less. Can you get FW in the winter where you ski, how big is your grey tank? Can you dump at the ski area? Not knowing the details of how you camp or your electrical needs it is hard to say if you need a genset or not. My guess you will run out of water before you run out of battery power.
