Having the truck settle 25% of the suspension travel when just sitting is normal and really is needed for it to handle properly. Its called droop. Without it when you corner and the outside suspension compresses the inside suspension many time lifts and without that droop the inside wheels would lift off the ground causing it to not handle well at all.

If you set it so it rides all the way up it will be very unstable when cornering or even on just moderate bumpy tracks.
