since i changed my mind and got the engine generator-i thought about how to keep just the cat's cool.
i've decided to take a shot with a swamp cooler. it is 12 volts and uses 3 dc amps per hour-it just uses water must get with the special 'air intake hose'-the intake hose is key
i will combine the fantastic vent,rear section windows refextict, and hanging reflextic blocking back seven feet of zion from front(one foot gap over this sort of wall). with the swamp cooler on the floor in the back facing forward. i hope to keep the space between the zions back beds cool for a place for the cats if they want it by using the 'reflectix wall' i will shrink the back area to less than 200 cubic ft.
i bought this swamp cooler and yes the total price with intake hose and extra filters was 450.00 dollars -it's for the cats-lol
this chart shows that humidity drops from morning to afternoon-which is the time of day the cats would need it.

i only need to keep a small area cool for them.
this video of a customer using the win3 part-he got the dual sytem gives me the idea this might work to a degree. remember though the temperature he shows is NOT his entire van-just the air in front of him i think this small section will cool the cats
one more thing i found out-humid air rises-i originally thought opposite i'm thinking the fantastic fan will slowly pull forward the warmer humid air
the temperature versus humidity chart 1/2 way down this page gives some info-if it is less than 60 degrees humidity-or closer to 50 humidity i think there is a shot
i will have this sensor around floor level in the back that can remotely monitored
