Hoping to get some feedback about Northstar Dog boxes. I am going to buy a box but not sure which one yet. I like the Molded plastic because it is lighter and easier to move. I suspect it will stay cooler and warmer as it will reflect instead of conduct heat and I think it is a little cheaper. I am looking at a 3 hole slide in that is insulated, has a fan, airing lights, Louvered doors and locks, bottom storage and a 15 gal. pressurized water tank. They gave me a verbal for $3800 new. I know similar boxes with Deerskin, Mountaintop, and Ainley are heavier and more expensive. Just trying to get some feedback from folks that have owned a Northstar and how they liked or disliked it as well as those who own other boxes. I would like to see a Northstar before I make a decision. Any info is appreciated.
