<strong>Yahoo Message Number: 4976</strong>We have a Select Comfort King-size mattress (dual chamber air bed) in our home -- love it. Thinking of installing a 60x75 Short Queen in our 2002 Allure.<br/><br/>Any comments about this or other brands for a RV? It won't have rounded corners -- is that much of a problem or inconvenience?<br/><br/>Do you have to let some air out before going up to a high mountain...
