No opinion on putting the dogs in back of the trailer.
Oklahoma will be too hot this time of year without AC. Back of the truck will be too, without shade.

Honestly, the way I'd accomplish this is by running a portable generator and connecting the trailer to it... How you do that safely down the road is going to be up to you.. On a Class-C with a defective onboard, I got creative one summer.

Or just buy the Mega-cab... It's only a few dollars more than a new generator. :-)
