We also have the Sleep Number King with the radius corners for campers and love it!
Had them in our house for years before going full time in the Montana.
Just remember if you are traveling and going to be going through different elevations the pressure in the bed will go up or down with the elevation. If you go higher be sure to lower the pressure before heading up there or the bed might over pressurize and blow a leak. We forgot to lower it once and climbed several thousand feet higher and the bed was like a rock!
