Cold Weather Start - What Can I Expect?

I just picked up a 1990 F250 4x4 with about 140k on it. I have been using the block heater to get it started in 35 degree wx (getting a glow plug check today at the dealer). It has had the disposable gp relay bypassed with a momentary switch, which seems like a decent solution. I have dosed the fuel to prevent gelling, as it was parked with Summer blend in it.

I won't always have the option of using a block heater, and it gets cold here in the Winter.

What is 'normal' for these engines in Winter starting? Without a block heater, will glow plugs routinely start these at 20 degrees f ? 10 degrees f ? Are there any special tricks I should know about cold starts? I'd like to avoid getting stranded until Spring thaw ...

This site is an amazing resource.
