High pitched "beep, beep, beep" when accelerating...

[okhmbldr]

I recently purchased at 2003 Holiday Rambler Vacationer, workhorse 8.1. It was a bank repo so I knew there would be some problems and repairs, but so far nothing major and I've been able to correct most. But, one thing I haven't figured out yet (there may be more coming):
When I accelerate a high pitched "beep, beep, beep" begins and doesn't stop until I stop. As long as I'm not moving it makes no sound, but as soon as I begin to roll, here comes the beeps.
I have no lights on the dash, so any suggestions? Thanks,

Actually I did have a beep sound from the jacks when I pick up the motor home. Filled with fluid and that beep and the light went away. But, I still have one beep working.

Do you hear the beeps if you are in neutral and increase the throttle?
