I like the puppy idea
I use a a ventilated bottom, with the mosquito netting on top, I strap every thing together well with multiple straps two on the narrow side and one over the long side.
Also a good thing to have is the beekeeper's best friend
It is a great thing to have to seal hives, cracks or keep multiple hive bodies together, so they don't leak bees.
Take your time and drive calmly and carefully
stop once in a while to spray the bees with water
