man, I feel left out
Jliao, I also sleep in my P5, sweet!!
I've used my P5 for biking, hiking (equipment), soon skiing (Okemo this weekend!), and sleeping in. The front seats recline very far back and I've slept comfortably up there whenever I'm alone and need to crash out for a night. I've driven to New Orleans twice and gone on other road trips and always slept in the back with the seats down (2 adults). It can get pretty cozy in there if you know how to set it up.
I guess I'm the only one here that goes skiing and not snowboarding.
For a rack I bought the Thule velo vise that has the extra bar that you can attach to the factory rack. I just ordered a thule 4 ski rack and some extra parts, trying to somewhat follow mtnbiker26's genius setup.
