We're planning on going to the ADGA nationals this summer & I have concerns about traveling in the heat. I have a WW stock trailer. Last summer we went from TX to VA, but it was June so not quite as hot as July will be. I bedded the trailer good & thick & stopped every few hours to offer water (with gatorade in it). Is there anything I should do to keep my does comfortable ? I did order some dog crate fans figuring that may help some. Should we drive it at night?
