We've used our camper twice a year so far, but we never planned for more than that really.
For a simple week-end away, we use the ol floating camper, as its set-up and ready to roll and we tend to use the terra firma camper for the time we go to Fraser, which we try for twice a year.
Because of work being season based (Lawnie), the warmer months are too friggin hard to get away on.
