A fellow owner was exceedingly ecstatic about their 13++ mpg average on their D. Unfortunately, they soon realized that their speedometer had not been properly calibrated. You will have to remove the shroud away from the dashboard to get the back of it where you will find some DIP switches. The DIP switches are readily seen. Set: 1 off, 2 on, 3 off, 4 & 5 on, 6 off, 7 & 8 on. On the small dip switch behind the tachometer, set 1,2,3 off & 4 on.
The DISCOVERY OWNERS ASSOCIATION, INC, was formed to promote the sharing of information and the camaraderie of fellow Discovery motorhome owners. Membership in the club is limited to owners of Fleetwood Discovery motorhomes.
