This is a WAG but I would suspect the headlight switch.  Another
possibility would be a chafed wiring harness, anywhere from the
headlight switch to the dimmer switch to the headlights themselves.

An easy test would be to unplug the headlight switch and start the
truck.  If the headlights then stay off, the fault is in the headlight
switch.  If they still come on, it's in the harness somewhere (or
someone has installed an aftermarket DRL module while you weren't
looking <G>)

Sounds normal to me.  As long as you maintain appx. 10 PSI for each 1000
RPM there's no need to worry.  Most engines have lower oil pressure at
idle than at speed.

good luck,

I will second the daytime running lights.  If someone put a module in it
like the Canadian cars come with, it puts the highbeams on half power
and leaves everything else off.

Or someone could have gotten creative after they blew the headlight
switch and wired a relay into the circuit so the headlights are direct.

I wired my headlights separate to bypass a poorly designed headlight
switch that only gave me yellow lights, even when new.  With the relay
in place of the stock switch, I have super white lights now.  I still
need to pull on the headlight switch to get running lights but have a
separate switch for the headlight relay.
