Best to know where in Kansas you are starting. I may be able to help.
^^^^^ This.
There are alternatives to 70/25/80, depending on where you are starting in Kansas.
Two points that could influence your route decision:
1 - E-470 around Denver. DO NOT TAKE! It's a toll road, and you'll be paying by the axle with a base rate of $3.55 for 2 axles then another $3.55 for each additional axle. and you'll have at least 2 toll plazas you'll go through, perhaps 3 (I forget where the one is right around I-70). It's a license plate reader toll, so you'll get it in the mail about 6 weeks after your trip. ($28.40 or $42.60 for the tolls, depending on 2 or 3 plazas).
An alternative is get off I-70 in Limon and take CO 71 all the way north....all the way to Kimball NE. It's a state highway, decent shape, and is fairly straight (read also boring) driving. It's 146 miles north, there's a half way point in Brush CO, if you need to fuel up. If you've got a full tank in Limon, it should not be an issue. This route, you avoid all of the congestion (which is now pretty much all the time) on I-25 between Denver and Fort Collins CO.
2 - Depending on where you are in Kansas, consider taking US 36 across the top of Kansas to near Idalia, CO, then take US 385 north to US 34. Take US 34 west all the way to Loveland CO, where you'll briefly pick up I-25 north to Fort Collins. In Fort Collins take Exit 269B west into town and follow the signs for the truck route through town to pick up US 287 heading from Ft Collins to Laramie WY. This way, you avoid all of the congestion of the approach to Denver, and the various ways to get through Denver, you avoid the congestion of I-25 from Denver to Fort Collins, and you avoid having to go all the way up to Cheyenne WY and save some time. It's not a difficult drive, lots of 3 lane between Ft Collins and Laramie, with good climb/passing lanes. Rolling terrain, but shouldn't be a challenge to your rig. And it's a beautiful drive as well. Pick up I-80 in Laramie, then follow some of the suggestions already provided.
As for fuel along this 2nd route, there's small towns about every 30-40 miles across the top of Kansas, and a GasBuddy app should help with finding diesel fuel. In Colorado on US 34, there's several goodly sized towns you'll go through and should have diesel available. There won't be anything at all between north of Fort Collins and Laramie WY for fuel (small station in Tie Siding WY, but subject to being closed and uncertain of they carry diesel). Fuel up in Laramie if needed.
