We have a Jayco 184BH. We have been very happy with it and have found it easy to tow even with something smaller than what you have. It's about the size you're looking at and has bunks. We travel with our 11 and 14 year old boys, and they have enough room.
There's also some SLXs that are smaller, but we liked that this one has a little couch, giving us someplace to sit when we are all in there. It's very, very small, but it fits our budget and has the basics that we need. We keep the dinette folded down as a bed and carry a couple of TV trays since we don't have a table inside with the bed folded down. Most of the time, we really aren't in the trailer all that much.
If we had a little more tow capacity, we'd really like a Jayco 264BH. Compared to our 184bh, this one has a dedicated bed for the adults instead of a fold-down dinette and has more room. It doesn't have any slides, so it stays pretty lightweight. You might check out the specs.
