Pix of truck. Crates on platform sliding drawers underneath (metal on doors is decorative). Side boxes with fans on top. Between crates is temp sensor and in box is 12 volt battery to supply power to fans. I used to carry a big marine one but this is smaller because I got tired of lugging it in and out and this thing can give me two days of fans. When I travel it is easy to take into motel ...you can see the black under the box.....still work in progress.
The fans are cheap O2 cool. One change I would make is the Endless breeze but these still deliver a lot of air. A friend is a welder. We are going to talk with him about cutting a hole in back of crate so I can mount a fan and pull air in from cab. I drive with the windoors open but it stinks during rain and on days when it is over 95 outside, I get very nervous with him in the back. Oh, the truck is 7 years old and those windows have gone 70mph plus all those years and the struts are still good. They are not "sliders" which are heavier and I have seen struts messed up on those without even doing that. I figure if I tear up the windoors, I get new ones.
. Keeping the dog cool is paramount. I like that I can lock the crates. I have all three latches engaged while driving, and when I stop someplace dicey I lock the door and the tailgate. [trust me, after having $600 worth of gear stolen on a search call.....there is no way to get he dog boxes out without the tailgate down and no way to get the dog out of the box without the key....I do NOT lock things while I am driving though.] I put the hardware cloth on the box because I am paranoid about paws because all my dogs have seemed to get their paws stuck-plus it keeps hands away from the dog and makes it hard to give treats etc. He is so used to being there since a puppy that he does not bark at people or dogs.
The ramp is tucked in to the side and under the platform you can see a box of cooling packs. I take my SAR pack in the house because it has medicines in it and it rides in the cab because it won't fit in the drawers.........but everything else stays in truck ready to go. Still plan to make sliding boxes to go under the platform in the corners and put a front on the side boxes .
