I am interest on everyones comments on your experence with w/ds. Have you found combos really useful or more of a use it once in a while in a pinch type appliance? I've seen alot of nice 40 footers for sale but none with stackers. So a 45 may be the way to go if stackers end up on the must have list. We plan on using the coach 3 to 4 months each year. Thanks for your input. Rick
