torn between 2 TT floor plans - toddler's parents need help!

Supposedly that is a 2012 30RE floorplan.

I don't see why you don't go ahead and open up the sofa around 7:30 for the kid. If you and the wife want to stay up later, then stay outside (that's what we always did when the kids were smaller). If you would rather stay inside, then do it quietly at the dinette or in the bedroom. You have a camper that is paid for and is a good fit for your size family - wait until your family is bigger or your child is older and wants to bring friends before you worry about getting a BH.
