Young family here (two kids under 3) and we use our TT whenever we can. Usually several weekends each summer with a couple of week long trips mixed in.
We did our longest trip this spring from MI to FL and back in 10 days. We love traveling with the TT for the kids because we can stop at rest stops and make lunch in the camper or have snacks and they get a chance to stretch their legs and play a little bit or eat some snacks or just use the bathroom. Over a 10 day trip with 7 of those travel days, we only ate out once on a travel day.
