Choosing the right Travel Trailer for our family

I will have a look at the models suggested. thank you.
We looked at the Coachman Freedom Express and liked it -- what do you love about it?

We are just not sure of what style is best for the children. We also like a Flagstaff classic bunkhouse model. are separate bunk areas a good thing? We do things together, but looking down the road, will teens want their own space or just leave the trailer all together and pitch a tent?

There is just so much out there!
