I'm seeing the WAS-RNO / RNO-WAS fare (~$122-124 o/w) on ITA, but am having a heck of a time finding availability on .bomb or others. Fare class is K.

There are a few routings available that drop you around the 6000-6100 mile range, hovering around 3.9 - 4.0 cpm for eqms. I had some luck finding bookings in one-way pairs, as .bomb kept giving me issues (perhaps I was not specific enough?).

There's a few options that allow you a 6:00am departure and 11:00am return the next morning (depart RNO at 8:00pm the same day) - giving a few hours in RNO to do whatever you please

Dates seem to range from latter half of January to March 9th - I'm sure someone can find something available during this time!
