We've been there -- about 35 years ago!
Did a bunch of back packing, station wagon camping and tent camping until the first baby came along. Then life suddenly changed.
Our first trailer was a 13 ft Compact Jr. that we acquired knowing kids were soon on the way. It was pretty basic, but worked out quite well for a young couple.
Next was a 21 ft Streamline we picked up used in Los Angeles. We did many enjoyable trips with that when the kids were little.
