We have a Sleep Number in our 2008 Berkshire, 360QS. I purchased it last year and installed myself. There was limited space under our bed, near the headboard side, but enough to install the pump. I used a hole saw and drilled a 2in hole right at the hinge of the bed platform and ran the air tubes up through it. On our setup, the pump is almost directly under the hole I drilled, then the tubes just run up to the front of the mattress. We have the 5000 series which has two bladders and a wireless remote control. After installing, I feared the air hoses were a little snug so I called Sleep Number and to my amazement, they FedEx'd extension tubes at NO cost. We would not be without ours - worth every penny to me. Regardless what you decide to do, good luck and safe travels.
