Is September a good time to visit Colorado???? How about crowds and cammp site availability in September??

Short answer: Yes!

A lot depends on latitude and altitude.

Camping is still quite good in September and into October. Kids are back in school, so family outings are reduced, particularly during week day trips. Weekends can still be a challenge, with the Weekend Warriors still heading out for that last gasp of camping season.

And campgrounds start to close down in September. For example, in RMNP, Glacier Basin CG closes shortly after Labour Day. Never figured out why, they could stay open longer, but that's just the way it is. Moraine Park begins shutting down loops in September/October depending on weather and conditions. B loop is open year round.

USFS CGs also start to shut down in September. Mid-September for higher elevations, and those in the northern area of the state. A bit longer, generally speaking, for locations in the southern portion. But again, everything is altitude and weather dependent.

For commercial campgrounds/RV parks, you'll find the season can run longer. For example, in the Estes Park area, there are places that stay open until the end of October. This to accommodate the folks coming up for the elk bugling in Rocky, and to squeeze out the last bit of seasonal income. And some places in southern Colorado will also have extended seasons, but again, altitude and weather dependent.

You can experience quite nice warm days, and crisp nights in Colorodo in September. You can also experience significant snow as well. It's all about altitude and latitude.
