We bought a 16 ft travel trailer new in 2007 when we still lived in Arvada. The size was fine for my wife and I, plus 1 or 2 small kids. We sold it last summer, as it was far too small with the kids now being teen or tween age, plus we had to store it in a lot because flat parking space is at a premium here in the foothills. I didn't really enjoy the towing process, and probably would have preferred putting the $$$ towards an older F350 and a used slider-in camper. With that combo, we could could work around the size issue with supplemental storage.
