One other drawback to this is that running anything else in the RV will lessen the time that the AC can be run, if at all.
So you can be sitting in a cool RV and not be able to do anything.
The same can be said for many of the other workarounds.
I am betting that this setup isn't cheap either. A proper genearator setup is likely more cost efficent and usable.
On edit... I just googled it $2224.00 !! Holy smokes. The large battery bank needed will just add to the cost
You can setup a pair of EU2000s witht he extended tank for less than that. And have a far more usable setup
