Thank you all for your help and making me feel welcome.
I'm in the East Bay - the vehicle was bought in Santa Rosa, and I bought the truck since none of our other vehicles are trailer-ready.
6.5 (!) quarts of oil (API SN), filter (K&N HP1010) replaced - I think my Τιτάν front is not stock - had to remove a bottom rock(?) pan with 6ea. 10mm bolts to get to the filter. The front looks different that what I've seen in photos. After the temps go down, I'll post a photo.
Had to prop up the hood - I wonder if the hood shock/pistons can be 'recharged' or just landfilled and replaced?
Also, noticed that the tire air pressure is OK, but the TPMS (?) thinks it's bad (sensors?). The previous owner had inadvertenly cut some wires on the body/frame (to put in a step) right under the passenger door and damaged the factory stereo in the process (!?). Aftermarket stereo works, but is not using the same wiring. Not yet sure how to use all its features (Bluetooth would be nice!), nor how many speakers it works with. Price one pays for a good deal ;-)
Exhaust sounds like a boat, and the truck is comfortable to ride in and see out of, inspite of the driver side window's buckled inside film,
