Take a look at this thread on PlanetIsuzoo (it covers both DOHC & SOHC): http://forum.planetisuzoo.com/viewtopic.php?t=16972

Looks like all of the timing diagrams for the 3.2L V6s that I have seen before. The reference to the 3.5L DI is a new one to me. I've been assuming it is a 3.2. Is the timing different for the 3.5L?

I presume by 'it' you are referring to the engine in your Trooper?
Check your VIN plate codes:
RLU = 6VD1 SOHC ENGINE
RLV = 6VD1 DOHC ENGINE

The VIN does not contain "RLU" or "RLV" in the codes. The full VIN is JACDH58W8R7925385. I am now working on a "dry timing" to see where the marks match. I have positioned #1 piston at TDC based on the timing mark on the lower cover. The left cam gear has been rotated such that #1 intake is just at the point where it engages the valve pusher (rocker?), and the right side cam gear has been turned so that #2 exhaust is at a similar point. I plan to put on the belt and rotate to see if cam gear marks align with anything meaningful.
I have another question. I removed the cam gears to put on new cam seals after we pulled the motor to replace various seals. I marked them so I am pretty sure they are on the correct sides. On the left side, as I face the engine from the front of the vehicle, the cam gear has a belt retainer lip raised on the front of the gear. The right cam gear is simply a gear. Drawings seem to emphasize that this is correct but if they were swapped then maybe that is the problem.

...The full VIN is JACDH58W8R7925385...
The code you're looking for is the Engine code which is also on the VIN plate, not the VIN # itself.
...I am now working on a "dry timing" to see where the marks match. I have positioned #1 piston at TDC...
Forget about traditional piston/valve timing when setting the Isuzu V6 - follow the instructions around setting the timing marks that you will find in the Planetisuzoo thread.
...I have another question. I removed the cam gears to put on new cam seals...
Sorry - I don't know.
EDIT - here's another good thread on Planetisuzoo specifically for the DOHC (look for Jerry's post in capital letters) http://forum.planetisuzoo.com/viewtopic.php?t=7674
