We are moving into a tri-level so I am hoping the stair thing is do-able because its only half a flight of stairs. I looked into those straps and I don't think its gonna be possible. When I went to pick the tank up I brought 6 guys (all college athletes) and we had a hard time sliding it on a wood floor. The tank was custom built and the designer used two 3/4'' panes of glass on every side. He also welded a complete steel trim around the top and bottom (hopefully I can get a camera here and post some picks). When I calculated the weight of the glass it gave me roughly 1500lbs empty. After 6 of us could hardly budge it we ended up tilting it side to side and manged to get a 1'' PVC under it then hooked the winch on my Jeep around it and rolled it down the hallway and up on to the trailer (the ramp was real long).
