No my trailer does not have the winter package.
In the winter when it sits at home I leave a 1500 watt heater running all the time. In Vancouver, BC we don't see the cold most area's have.
Our day time temp is usually close to 40 and at night dips to just below freezing I have the electric heater set at less than half power and it holds the temp at between 55- 62 .
I could use the furnace
which works fine but because I have electric hookup available its easier and quieter.
My trailer never saw much use till I bought it other than having to spend three day's polishing the outside to bring back the finish as it looked chalky from not being looked after.
Inside my trailer it is in great condition I had air conditioning
installed last Aug. because the area I camp is desert and temps go over 100 I needed this. I put in a 9200 btu unit and it works fine at less than half power.
My unit only had 15 amp service so I had to upgrade my electrical
service as air conditioning
requires 20 amp service.
I also changed the brakes
last summer and put Dexter never adjust on the best thing anyone can do.
