Need help finding first travel trailer

We have camped near ski resorts in a tent trailer and both of the hybrids we have had (still have one) many times. We've always been comfortable. We are typically boondockers, but not in zero degrees! It's the only time we hook up. We take electric blankets and down comforters. We run the heater all the time, even when we're on the slopes. We open the cabinet doors to keep water pipes from freezing. We use a hose heater for the connection from the rig to the water. We do this because we love the hybrids the rest of the year. Word of warning - if ice collects on the outside, don't knock it off. DH kicked one off and the black & grey water handles came with it!
