I am not sure an APC would be the way you want to go. I have hundreds of them installed at 50 sites I manage and we replace about a dozen a year, almost always sites out in the county that are prone to frequent power outages. The batteries will last 3-5 years if never used, but you would be lucky to last a year if you drain it completely once. All you have to do is forget to turn off the APC once when hitting the road and let the battery run dry and all you now have is an expensive power bar. Also you may find in some campgrounds where you have poor power, every time there is a brownout it will beep. If it beeps a few times in a single night, you will want to throw it out the window.
