My advice: it is usually much warmer when pronghorn hunting than compared to Deer firearm season.
Bring 2 big coolers with ice, get the body on ice right away, whenever you break it down put the parts in the other big cooler with ice.
Unlike deer (or larger animals) you don't really need to quarter in the field to haul it out, they are so small that even walking you can carry them. Also unlike other hunting we always would drive 4 wheelers or side by sides around because you're covering so much ground and its ground that can actually be driven over. Totally different than mountain or forest hunting.
Last time I went pronghorn hunting (October 2019, Gove County KS) it was 96 degrees and I sweated so much I ended up throwing my old hunting boots away because there was no coming back from what I had done to them.
