Select Comfort!!! YES!!!! We put a double size Select Comfort in our last TC a Northland 950 Polar. We immediately fell in love with the total and complete comfort over the standard mattress. We had to learn that every time we made major elevational changes we had to adjust the air setting. We use a very small inverter plugged into a 12 volt plug in the cab over. Works great. The next big hurdle we discovered was camping in realy cold weather the Select Comfort seemed colder than a standard mattress. We found a simple solution we put a really nice memory foam Mattress Topper "under" the Select Comfort Mattress and we now have been thoroughly enjoying great sleep for almost 10 years of TC'ing with Select Comfort. We encourage all to consider the the Select Comfort advantage.
Happy TC'ing
