ISL 400 engine thermostate
I have a 2008 Thor Mandalay with a Cummins ISL 400 built in 2006. It calls for a 180 degree thermostat. Has anyone put in a 190 or 195 thermostat? DO you foresee any problems by going to a higher temp...

Not a good idea. Prior to electronic engines, it was common to change thermostats values for one reason or another. These ISL engines with the tight fueling requirements and multiple sensors feeding into the ECM are looking for very specific running temps.
What it your reason for wanting to go to a higher temp unit?
X2.
Your ECM is programed around certain parameters. No way would I change it.
