A problem with the relay won't manifest itself until you really need the extra cooling. I know when my max fan kicks on, it sounds like an airplane taking off.

You are correct, I remember the same fan issue cropping up on a few. I've never actually heard mine like you guys are describing while pulling. Mine is an early production 11'.
I will agree with you 93Cobra2771.
I have not had any over heating issues and have towed my 5er in some very hot weather and some long up hill passes over the past 4 years. I have only heard the fan cycle on/off while maneuvering my camper into a spot and even then it wasn't for very long.
What temp thermostat comes stock in these anyway? Maybe those that have problems need to check theirs and put a lower temp one in, make sure the fins are not bent over or check and flush/change the coolant system.
