It would be helpful to understand your truck's capabilities. Since you have a family of 5, the smaller the trailer the less room to be comfortable as a family. The bunk house can be a place to sit or play if large enough, but typically just a place to sleep. We were in our trailer with our 1 son and 2 dogs this weekend and he was complaining about having a good spot to sit and watch TV with us. We have a small sofa and a dining table, but no where to really sit and watch TV. OK for 2, but no way would be have enough room for 5. We have a 5th wheel which we bought because of the quality and bunkhouse vs the TT's we looked at. So, a larger trailer gives you more room inside, but then harder to find a spot at some campsites, specifically state sites.
