I was just going to mention the washer and dryer being a problem.
We are a family of 2 left at home. We started looking at everything from pop ups to class A. We hadn't a clue what we wanted. Anyway...after looking we went TT.
Can I make a suggestion....go bigger than what you could be happy with. We ended up with a 27'. There are bunks we use for storage but it is hard to find anything a bit bigger without them...you need a bed for your son, he will grow. I would make sure his bunk is a double.
On a wet day, no matter how well you get along you will quickly learn how small an RV can be. Your son will need a place to play either floor space or a bunk.
Our friends settled for a smaller TT with no couch. There are only 2 of them. They find it uncomfortable having to sit at the table all the time. They also find they do not have their own space.
I do not have enough knowledge to suggest a make/model for you.
Happy travels!
