Spearfish to Las Vegas

Why go so far west to go south? I would go south to Cheyenne to Denver to I-70 to I-15. That's just me.

Doesn't your GPS have a setting for 'fastest' route? That route is more likely to use highspeed highways, as opposed to the slower 'shortcuts'.

you could go as far south as I-40 to turn west. Doesn't 80 go higher than 70?

I think this ^^ would be the best, with a slight alteration. You're going to have a few spots without cell coverage no matter which way you go, but I'd suggest I-90 to I-25 to Hwy 287 to I-80 to I-15.

That said, with that route there will be a pretty good stretch from Casper to Rawlins that's quite remote. If you're very concerned about that, do this one:
I-90 to Hwy 59 (Gillette) to I-25 to I-80 to I-15. Hwy 59 is a busy road with more traffic than I-90 or I-25 over most of it. Cell coverage isn't bad either.

90 to 25 to 80 to 15 seems a better choice
To me.

I am trying to return home after a long trailer trip to Alaska but the trailer keeps having towing break downs so I am trying to find the route with fewest climbs,, road assistance if needed and cell coverage. My GPS always puts me on in the shortest, but often remote routes with grades and curves. Any suggestions? Thanks Sandee

I'd stay on the major highways, 90 west to 25 south, to 70 west to 15 south. You will have to cross the rockies expect a few grades.
