Why do people have such large trailers?

We started in my Dads 32' Winnebago that did not have bunks or a slide. He wanted us to buy it but we bought a 27' Wilderness that had 4 bunks but no slide. It was a little tight on rainy days with two kids and two adults. So we sold it and traded up to a 30' Sunnybrook with 4 bunks and a slide. Now we have the room we need and so does our daughter in the back. She can close off her room for privacy, so can we and we bother have the living area in between. On a recent trip with rain we had plenty of room for games and movie watching and even when cooking. However this is my limit on a TT. It is big in the mirrors and will not fit in every site. Eventually we are going for a fiver. That will give us the larger bedroom living area, and even though our daughter is effectively out of the house, we will still get a rear bedroom area. Some of them have a rear den that converts to a bed. That might be it. The size will be dictated by the floor plan, especially as we spend more time in it, its like a second home, not just a weekend fling.
