I often se get the Champion generater instead. But just read some reports yesterday that several said it would not run ther air conditioner, and some said depending on conditions it may and may not.

In order to make the most sense of reports like this, ideally you'd want to know the make and model RV a/c unit being discussed (to obtain the continuous current and LRA ratings). For instance, there are very efficient 13.5k BTU RV a/c units (LRA ~50 amps) made by Coleman-Mach that can be started (and run) by a smaller Honda 2000 watt inverter generator. These very efficient units are rarely used for OEM installations and must typically be special ordered. On the flipside, there are some very inefficient 13.5k BTU RV a/c units (LRA ~68 amps) that even a larger 2800-3000 watt generator can have trouble starting. You'll see inefficient units like this used quite often in OEM installations. The BTU rating of an RV a/c unit only gives you a very general idea of the power necessary
to start and run it. If you know the continuous current and LRA ratings of an RV a/c unit it can definitely give you the upper-hand in finding the best generator for the job.

As TomG2 already commented, Champion makes a large assortment of open-frame and inverter-style generators. We've owned a few Champion generators in the past---they're good generators that offer a lot of bang-for-the-buck. Just got to make sure you choose the one that's most appropriate for your application. Good luck!
