I, too have a 2024 Bounder 35K. Had it since June 7. You'll have Ford's Godzilla engine, the 7.3 V8. Plenty of power. However, when it is pushed, especially when going up a hill and in hot weather, the fan clutch will kick in for extra cooling and it will sound like a jet engine. But, will last a very short time.
Enjoy your new coach!
