Jennifer, we love the Cannondale Tandem....we've had it for 4 years now. It would fit in the basement storage if I didn't have so much other "stuff" in there. My coach is only 36' long so my through storage compartment is about 1/2 as wide as others I have seen on 38' and 40' coaches. If I had the extra 24" of width I would put the tandem in there. I have a rack that slides into my receiver hitch, and a cover for the tandem, and that is how I transport it. Cannondale makes a wonderful product. We also have individual Cannondale bikes (Bad Boy for me, and an F600 for Elaine), which have the patented Headshok.
We'll be taking it on our long trip in November/December. I would recommend getting headsets for communicating. We tried it without for a year, or so, and then I bought the wired headsets and no longer had to turn over my shoulder to talk to Elaine, which takes your eyes off the road. You can also plug your IPOD in to it and listen to music while riding, if you like. As soon as you start talking it interupts the music. I got it here:

Enjoy!
