RoadTrek Sprinter RS or CS Adventurous for family of 5

I would question your waiting until the children are older. Mine were 2 years old and 1 mo. old when we went on our first when we got our first TT. We have had at least 1 RV at all times since 1969. Now the youngest has a Wanderlodge and oldest (50) is looking at a van or using my RT at times.There are many memories from their younger years and at 12 for the oldest it may be too late to get them interested in RVing.
