I have looked through the package of manuals that I have and can't find any information on the air conditioners. I want to know what the BTU rating of each unit is.
Has anyone successfully upgraded their A/C units with larger capacity units?

This info is usually contained in your original product brochures. Or if you received a list of 3rd party items installed and their part number and serial numbers you can simply Google the part numbers to find out.
I don’t know if your Sighteer came with one of those sheets or not. My Adventurer did and it also includes my VIN and Winnebago serial number too.
If you don’t have a copy of your original brochure Winnebago.com has a brochure archive online.
I have the same rv, the ac units are 13,500 btu. You could up grade to 15,000 but it will not help that much and it would be an expensive upgrade. The one advantage of the smaller units is you can run both on a 30 amp service with the refer on gas. The big problem is the sun loading, if you can get the rv in shade or partial shade it will help tremendously.
