As far as...
...where to camp?
...how to use your trailer in "cold" weather?
Weather records show the high/low of February '17 was 73/32 degrees with a historic average of 63/33 degrees.
Keep the propane tanks filled, your furnace functional, bring an extra blanket, set the thermostat at 70 and bring irish cream for your coffee in the morning!
In all seriousness, those temperatures shouldn't really be of any concern as the lows at night dip to near or right at freezing; however, those are for very short periods. If you were in MN and in less than 32 degrees 24 hours a day, you'd have a different set of concerns.
