dealership scan advice

I know that this subject has been beaten into the ground and I've tried to do as much research on it as I can but I'm at my wits end with my trucks cold weather starting issues. First of all I've done everything recommend by everyone on this forum and here is what I've done or checked, batteries are good and about a year old, new stancor (about month old), last winter new glow plugs and undercover harness, recent fuel filter and oil change (synthetic 5-40), I tested gpr/glow plugs to make sure I did it correctly and only one glow plug (drivers/closest to cab) not giving good #'s. I should of written down the #'s after each time I tested the gp's and gpr because someone is going to ask what I came up with but I didn't but they came up good compared to testing procedures others have posted on here. The truck starts fine in the summer (no smoke) but starts showing problems when it starts sitting out in 40 degree weather overnight and gets worse as it gets colder with white smoke when trying to start, it starts fine when plugged in, my worry is that I work long shifts (10-12 hours) and I can't plug it in at work so I have to go out at lunch and start and warm it up or risk it not starting after sitting all day at work.

So on to my question, if everything that I just mentioned above is good (which I'm really sure is because I've tested and retested), what would you look at next? low compression?, injectors?, hpop? other? I don't have or know of anyone that has an autoengineuity so I was thinking of taking it to the dealership to get scanned. And I know this is a dumb question but what all will their scan test? I assume the hpop and injectors but a compression test would be separate test? (and again I assume pretty expensive for them to do) if I'm going down the wrong road please tell me as I don't have the money to start throwing at it. And if anyone knows of a reputable diesel shop in the south Kansas city area I'd appreciate any recommendations.

how did you test the GPR? did you try jumping the gpr cold? how do you know it's being commanded on?

I used a multimeter first to check the batteries, then from a ground to the always hot post, with the key on from ground to the opposite post, and then ground to the red wire post. I knew it was good being its new but I checked anyway, I also used the multimeter to check the harness. I don't remember if in my signature I mentioned it has 290k on it, I bought it with 190k and as far as I know it has the original injectors although I put new injector o-rings this past summer.
