Recommendations for our family

We are a family of 5 with our three kids between the ages of 7 and 3. We have a fourth on the way this fall. Currently, we have a pop up but are looking this fall/winter to upgrade. Ideally, we would find a TT that has 2 sets of bunk beds but those seem hard to come by. The other kicker is, we are using Durango to pull so I’m not looking for a 32 footer, the shorter the better. Any ideas or suggestions appreciated!
