I would recommend updating your glow plug relay set up. They originally came with a timed system but there have been a lot of problems with them not putting out enough or just shorting out. I actually updated mine to the same relay as a 97 powerstroke. They get hotter that way, so I removed the timing setup and just have a button that I push for about 4 seconds and then increase the throttle knob. I bought my truck from an Idahoan and happened to live in St. Anthony for 3 years of owning my truck. Without the update I would have had to plug my truck in during the summer. I've had the truck for 4 years now and 40,000 miles and have only replaced the glow plugs once, so if you are careful they can still last a long time.
I usually only plugged my truck in once it got down to below zero. Otherwise it was just to much work for my battery to warm my plugs and turn the motor over. If it's parked outside and the wind is blowing (when isn't it in Idaho?) I would start plugging it in when it'd get down to about 15 degrees at night.
