Here is another vote for the Passport 2910. There are lots of great floor plans out there and this one works for us. Other then having a dedicated bed for each kid, we love the deep slide that the 2910 gives over some of the other similar models.
What are the ages of your kids? If you are considering putting two in a bed, with my current 12, 9, 7 and 5 year old I am willing to bet that only 50% of the time we would be able to get two to sleep together nicely.
Do you already have a tow vehicle? Just wondered what your towing limitations might be.
