Loud Noise at Key Turn

Don't even have to start the rig, just turning the key will produce a VERY loud roar/growl that lasts for about a minute and then stops. Our repair person said he thought it was the air horn priming itself, but the noise didn't happen when we were test driving the unit and until after we had driven it a couple more times. Any ideas?

It's a 2003 33' Firenza MH.

That does sound like the air pump priming the system.. It could be leaking air and the previous owner did a cheap quick fix to get it sold..

If I remember correctly. The Firenza is a gasser. Likely a Ford. Just a check. Next time you hear this noise, see if the engine is NOT running yet---and your foot is pressing the brake pedal. Just about every Ford Class A, will make a roar if brake is depressed and engine is off. No problems, just a type of reminder.
