We've hand ours 2 full seasons, and get out as much as we can. Typically we to mostly 2 night trips, a couple 3 nighters, and at least 1 full week. Look at my signature. It's based on that time. More is our plan, but work and life gets in the way far too often.
Typically we start in mid to late April, and will winterize in November. The camper is dry enough and if power is available to 400 watt will do just fine keeping you warm enough to sleep comfortably.

The only thing that will keep me at home is cold that even my home furnace and pellet stove has a hard time competing with...like we are about to experience (Monday is a projected high of -1)
I know 20 degree nights are doable, I have. but there does come a point where it becomes work and not fun. If I were full timing nomad like bear and Jenn it wouldn't be a problem...about November, I'd move to greener pastures. Florida and Georgia are both fine places to be in January.
The other stopper is salt on the roads. I know CI does an awesome job, frankly the best I've seen anywhere in the RV spectrum, but it's a peace of mind issue for me. Maybe if I can finally get mine treated with an aluminum sealer this will change a little. But I doubt it.
My ultra 560 is also my port in a storm. Especially in spring and fall....12 volt lights, Television, and a full working galleys with refrigeration (dometic 12 volt) and power outages a non event. I'm good for about 2 to 3 days without skimping. More if I turn off the TV and plug in the solar panel. Throw a personal generator that runs as 62db and can run for a couple days on a 40lb propane bottle and you've got AC...all the comforts of home. If the situation doesn't improve in those 2 days, hook up the tow vehicle and go some place else.
One bit of advise,...keep yours loaded and ready to hook up. We have camping wardrobes separate from out daily wear. We keep the camper ready to roll except for the final packing of meat, bread (liquid as well) and other parishables. We do keep a stock of dried foods as well. Simply for convenience. If on a Friday we decide to leave right after work, packing is a 15-30 minute ordeal....we can be rolling in no time, This is something we couldn't do before we had Serenity.
Darn it....now I'm thinking camping and am 10 minutes late for leaving for work,
