Interesting on the misting system. I have the same motorhome you have. The only difference is mine is a Tioga otherwise I wouldn't be able to tell them apart. I have had overheating issues since I bought it used while towing long grades in 80+ degree weather. I have replaced the thermostat, fan clutch and flushed the radiator and nothing has helped. Have been thinking about replacing the radiator to see if that would fix it however infared heat gun seems to show no cold spots in the radiator. I also bought a mister system from a retailer but didn't mount it because I couldn't find a suitable location to mount the tank where I could fill it and drain it easily. Have been thinking about making my own mister system and tie it into the fresh water tank. What did your mister system use as a water supply and how was it activated? Thanks, Jeff.
