Are Hybrids growing in the US?

In the early 2000's Hybrids were everywhere in my area. All dealers had numerous selections. Lately I'm seeing fewer being sold new although I see quite a few at the campgrounds I frequent. They're still popular but not to the extent of 15 years ago.

We loved ours for 10 years. Never any problems and looked like new when we sold it. But the kids grew and we no longer needed all the beds and wife and I switched to a 5th wheel. Already had the 3/4 ton truck to pull it.
