Hi, Redneck, funny you should ask! I was just coming back here to thank iddee, again, for the helpful information!
My dad went down with me and was going to help me drive, but about 4 hours after leaving our place, his left eye went wonky and I ended up driving most of the way down and all the way back. Looooonnnnng trip. The way back was exciting. The Siskiyous were quite refreshing after the rain/hail/lightning storm we experienced through Weed. A lovely city, I'm sure...during the day...when it's sunny... ;)
The bees did great. Iddee, I ended up leaving the big doors shut and just opening the sliders (on the driver's side). We had pulled the plex on the passenger side. My biggest concern ended up not being high heat, but wet, due to the sideways rain. The bees held up great though. Ventilation and temperatures were good. My husband purchased a thermometer, which we placed in the middle of the packages. I could read the temps from the truck. It was interesting to keep an eye on the fluctuations as we drove.
What packages didn't sell got hived into 5-frame nucs. Got those all sold, too. All in all, a good trip and a positive experience!
