However, it's clear that the air conditioner will pull more than it's rating at start up. So for this scenario do I need to choose a smaller AC unit, only keep one connected at a time, or is this really not going to work without a 30A service?
Thanks guys

A "regular" receptacle can be either 15A or 20A depending upon the house wiring (in the wall). What do you have or want?

If you can find an AC unit with a 10.5A rating then adding 4 amps of charger puts you right at the 15 Amp limit. I'm not sure what you are going to be charging at 40 amps continuous, but my guess you will be much lower for example at C/10 for 100 amp hours is only 10 amps. Haus (deep cycle or lithium) batteries are not going to be wanting a C/10 charge continuous. The controller should go into float and much less current. So we are possibly overestimating the charging demand; I don't know what your battery setup is?
Given what is probably your objective. I would say that if you got the 10.5 Amp rated AC cooler with the smart converter recommended

then you can run both AC and charger as long as you are not going full tilt with charging. If you have a 20Ampo service then no issues all the way around.
There are plug converters so you can plug the 30Amp cord into a "normal" 15/20A receptacle.

This way you can plug into a 15/20A service normal outlet or the 30Amp outlets at RV parts. You will have all the functionality you desire running off off the lowest 15A service as long as you do not go full demand continuously.
If you are running in an RV park or other unknown circumstances you will probably want some type of surge protector such as the following.

Of course, if you are always going to run in your driveway under known conditions, and you watch your loads (someone living in the RV in the driveway) you can cheap out and just go with a "regular" plugs for the RV. As previously suggested.

Note: "Watch your loads" means.
- Do not Turn ON the AC unit when you have known Max/high charging demand.
- Turn on AC unit with Charger OFF.
- Turn on Charger only after AC unit has started or is OFF.
Of course, the real cheap out mode is to put a $200 window mount AC unit into one of the windows in the rear. These have no problems running off a 15Amp circuit.
