I use a couple of soft duffle bags in the front and then strap a soft suit bag behind seats. Normally this is plenty for 3-4 days for two if you pack lightly. Additionally I always carry the space saver spare and 2 cans of foam.
For the upcoming 71/2 hour drive to the FFQC, I am thinking that the best thing to do is UPS my tux and my wife's evening gown for the black-tie ball to the hotel on Wednesday and just pack all our casual clothing, ect. in the Boxer luggage. We'll likely have to have our formal attire pressed when we get there anyway.
Jeff I just received the Nichols book from Amazon. Good read. Thanks. Interesting how the different sources diverge. All adds to the folk lore. Philip
