Fourteen feet of travel trailer with a full bath is a genuinely rare combination, and the Polar Bear BASE pulls it off without breaking the tow rating. The double-insulated roof. Foam board plus radiant barrier. Means this thing is built to handle temperature extremes, backed up by both a 5,000 BTU AC and electric heat for year-round flexibility. Inside, birch cabinetry gives it a warmer, more finished feel than you'd expect at this size, and the MaxxAir fan keeps things comfortable when you'd rather not run the AC. At under 3,000 lbs, it opens up the tow vehicle list considerably.
Other travel trailers floor plans (around 14 ft), similar in size and price to the Polar Bear BASE.
