I have a Keystone bullet 281bhs and would recommend it as well. It's great for kids because the double bunks are a bit of a "hidy hole' so the kids feel like they have a "room". It has tons of storage space and cargo capacity -- 2400 lbs. With the double bunks, it also works fine for teens. The U-shaped dinette is a good for accommodating more for dinner than the bench dinette and there is seating for six after dinner. One of the things that is tough is alot of rigs have tons of sleeping, no place to eat or sit in the evening if it is raining. I spent a long time finding something that would not put my SUV over the limit with room to spare and the 281 BHS was the best bang for the buck and weight.
I have towed this combo with a 2005 Dodge Durango Hemi in Colorado, etc -- I do have Bilsteins on the car and if I were keeping the bullet, I might add airbags. The 2005 Durango has, I think, a 7200 lb tow capacity, and 1000? hitch weight. The biggest issue is the wheelbase, so I also have a blue ox weight distribution hitch. I don't drive 75 mph, but you shouldn't do that anyway. It's gone east to west and back twice, so I know the combo works fine.
Here's some pics of my rig inside and out: http://washingtondc.craigslist.org/nva/rvs/3958565714.html
