Never had a problem with compressor, this is our 5th sleep number in the family, and second in RV, if you are going to change(increase altitude while traveling more the 4000 ft) we usually drop the pressure to #20, and reinflate at camp. Sleep number has store in most areas now. With one day delivery, don't think getting something is a problem. But then again in 13 years never need anything replaced. Our mattress showed its teeth within a week or so, of sleeping on it, hope you got a good one. Being a wizard at computer, hmm, maybe we will cross paths some day and barter for computer tune up for wood working.
Enjoy your travels and we know you will love the rig. What are you towing with?
