You should first check your Glow Plug Relay.
There are 2 relays that look alike. The GPR is the one closest to the firewall. A quick test would be to short across post 2 and 4 for about at least a minute or more at the temps you are talking about. This will energize the GPs. Then immediately try to start the truck. If it starts easier then the GPR is faulty.

that is correct, you can jump the posts to get out of a jam or swap the relay out for the one in front (AIH) but tape off the wires real good so they dont short out, until you get the new one in.

Remember that they dont come on if you have run it earlier in the day or it's hot. Just a thought...

I did this three years ago and haven't changed it back.

No maybe took a bit of life off the batteries and maybe the starter but you'll be ok.
