coolant temperature changed
I have had this coach for about 3 years. The engine temp has always ran about 195 to 199 degrees unless it was very hot outside(90 to 100 degrees). On those very hot days it would go up to about 205 d...

Cleaning the radiator was good starting point. If the coolant maintenance has not been done in a while I would agree that doing it would be a good next step. When it was done did were the thermostats changed? Even if the thermostats have been changed then I would recommend having the thermostats changed again. That would give you a base line to continue to troubleshoot.
Inspect the cooling system to see if any of the hoses are kinked.
Is the fan running more often with the higher temperatures? If the temperature continues rise the fan will continue to run more and more. Having the fan run more often will hurt your gas mileage.
Here is another thought. Are you using the Dash AC? On my rig when you turn the Dash AC it turn the coolant fan on full to cool the AC condenser coil mounted on the front of radiator. For troubleshooting you may need to have the AC off to get a consistent temperature readings.
Are the readings from the dash gauge or from the engine computer using something like a Silverleaf? The engine computer will be more accurate and much more responsive.
All though the 200-205 degree aren't are not "horribly" high, based on the fact that it was running at 195 and designed to run at 195 the increased temperature should be investigated.
