I didn't find a CB necessary. It might have been nice on the haul road. This I my trip report http://www.expeditionportal.com/forum/threads/34534-Alaska-2009 . Hope it may help.
From reading your build thread it doesnt look like you took too much stuff =) I think you and I are opposites when it comes to packing I have about everything under the sun to take with me.
Your write up is fantastic though, read through a bunch of it last night going to highlight a few of your better stopping spots and make sure that we check those out. We are not planning on going much farther north than Denali as we only have three weeks off work and have to be back for a big Spartan Run on the 3rd of August.
Had a great day out in the garage yesterday. I got a cool little mount built for my bottle jack that mounts it right on the bed for easy access if needed on the road. Fixed some damage on the rocker panel that I did up snow wheeling so that the rear door now opens and closes nice and smooth cleaned up and painted that area as well and it looks descent.
Got power run from front to back for the ARB cooler and fired it up. It ran good for several hours but then once it got down to 32 degrees it tripped off on low battery voltage. The cutoff is 11.8v but the truck fired right up and ran like normal. I am wondering if I ran too small of a wire back there and am getting some kind of voltage drop front to back. Need to check that with a meter this weekend and see what's up. Cooler ran well though its quieter than I thought it would be.
Built some brackets for support on the front inner fenders to try and help out with a few rattles and squeaks (worked like a charm).
Changed the oil and filter.
Topped off the coolant.
But the best thing that I did all week was to get the condenser in there along with all the A/C lines and a new filter drier, evacuate the system and recharge it with some new r-12!! With the temps in the high 90's here last week the A/C was definately on my to do list before we headed out on the trip.
My buddy Chris came over and we got the ARB Canopy hung on the side of the trailer. I have got to say what an awesome product this thing is. Was really easy to install and self supporting. Cannot wait to see how it works on the trip.
