Not knowing for sure, I wrote to Norcold and asked if hurt the unit to run it all summer since I camp about every other weekend on the average.
They answered that it was a personal preference and that running it continually didn't take away from the life of the unit.
We start our fridge in early May and shut it down in September. After 7 years still no issues, my home made fan kit is still running as well all this time.
