Considering our camper sits at home, in our drive way, I have electric hooked-up, and a proper way to dump the tanks, we use our camper every day. We fired everything up April 1 this year and we'll keep using it till we get snow (or maybe even longer). We sleep in every night, nothing like full timing in your own driveway?
I was talking to my wife, just this morning, if our son and grandson were not living with us, we could just shut the house up, leave the water on and one water heater in the house so we can do laundry, kill the power to absolutely everything else and just live in the camper. But with our son and grand son living with us, that's not possible. Hopefully, they will be moving out someday!
We take 2 one week trips every year, one in December around Christmas time and the other the second week in March, or however March 10 falls. Those two weeks we go to Florida and/or South Carolina.
During the warm months, we take the camper out "almost" every weekend to a couple state parks, and usually a week (sometimes) 2 week around the middle of July.
The bigger question is, how many days a year does our camper NOT get used. The answer is ... about 30 days a years it's closed up.
