It appears the GY Endurance max psi is 80, so would I have to get different rims that would allow higher psi?

The Goodyear Endurance in that size are rated as a load range E tire. They would require 80 PSI to provide 2830 lbs of load carrying capacity. This would increase the reserve load capacity, something that seems to be marginalized by RV manufacturers.
If you do go this route, please be advised that the wheels must support that PSI as well.
As a side note: if the wheels do not support this load, Carlisle makes a good Radial Trail HD ST tire in load D that will match your current OEM fitment. Here's the chart for reference:
