Re: Long tow this winter
1st get your truck and trailer serviced as stated
2nd, you don't go through Colorado or any real mountains until you hit the Utah border on I80 as you leave Wyoming. But when you get there, that mountain is real, and the grade is steep and it's long. And then you have to go down it to get into Salt Lake City. Be careful!
3rd, the topography is flat as flat can be, basically, until you get into Wyoming. Then it starts to gently roll. It's actually quite neat, if you are into watching the gradual change of topography. It's pretty hilly by the time to you get to western WY. With exposed rock faces on the hill slopes.
4th, there is a upward slope starting in Iowa somewhere and it will continue all the way until you come to that mountain at the WY/UT border. So if your truck seems to be working hard and running warm, it's because it's pulling something like a 3% grade for about 1000 miles!
I went from East Liverpool, OH to Salt Lake City with my dad in his 1981 International cab over pulling a 6000 gallons of Quaker State oil in a tanker trailer, when I was 10 or 11 years old. So it's been 25 years, but I remember all this from the trip.
I also remember that the caribou or deer or what ever the heck they are, are EVERYWHERE in WY. And they don't seem to mind jumping that fence and crossing I80. I wouldn't travel at night for this reason.
Lastly, the blowing and drifting of snow is a real concern. The wind blows pretty much west to east, but if it comes out of the north or south or when the road bends that way, drifting is a real possibility. Also, the constant headwind, along with the aforementioned grade, will cause your tow vehicle to work EXTRA hard. Be prepared.
If you make it to west of Chicago and the wind or whatever is just too much, I know an outside storage place in Peoria that you can rent for $20/mo on a month to month basis.
I will say, that at the end of your journey, as you come down that mountain, and see the city spread out across that huge valley and starting up the mountain slopes that border it, it is easy to see how a group of religious people could think that God wanted them to stay there. It is truly beautiful and if the sun shines off the golden dome, it's angelic!
Enjoy the trip!
