Question:

I have a 2014 Keystone Carbon 327 with 16 x 6 aluminum wheels. 110psi is stamped on the inside of a wheel spoke. Does this mean 110 psi max pressure or cold tire pressure? The rv came with 235/80R16 E at 80 psi. Based on the above information can I go up to a G rated 110 psi tire?

Yes, if the existing wheels on your trailer indicate a psi rating of 110 with a stamped number this would refer to its max psi. Typically on a trailer wheel it isn't really the wheel itself that dictates max psi but the valve stem that is used. An easy way to further verify that the wheels are setup to handle psi levels of over 100 is to take a quick glance at the valve stem.

If it's completely metal like the Americana # AM20906 then you're good to go. If it's all rubber or even a portion (such as with the Americana # AM20907) then you would just need to change it out with a higher-rated unit like the one mentioned, which will fit without issue.

If your existing valve stems are all metal or you change them out to the appropriate units then you can absolutely swap your tires out with a Load Range G like the excellent Provider ST235/80R16 # PRG80235 you were looking at. This particular radial ply tire features a 4,080 pound weight capacity at 110 psi and a speed rating of 81 mph.
