In February of 2017 I purchased a 2010 313rks to begin full-time rving. We actually just started living in it on Thanksgiving Day, camping locally and plan to head out of the area around spring of 2018 when we both officially retire. I've documented the process on my website
Home - RVing.Website. As my luck would have it, this area of the south that usually doesn't see cold temperatures until February started out cold as soon as we moved out of the house in November. It's been keeping warm in the trailer though. I'm going through about 30lbs of propane in a week with temps in the day around 45-55 and dropping at night to around 30. In the day with a sunny spot it really holds heat well. The basement area doesn't seem to get too cold but I shut off the water when we are both out of the trailer for the day as a precaution. My water tanks are not heated. The only negatives I have for this trailer is the kitchen area takes a serious beating when you travel. I don't keep canned goods or any other items of serious weight in the cabinets. The other negative is the overall weight of this beast. My TV is a Ram diesel 2500 and I'm right on the edge of every weight (axles, pin, hitch etc). Still working on bringing that down as much as I can.
