Guess no one has ever been in parts of the country where people hunt with dogs? Its totally common for hunters to have kennels in the back of their trucks for their dogs. No one wants a wet muddy dog inside with them! How many jack asses do you see every day driving down the road with their dogs loose in the bed of the truck? I personally adhore that idea. But its done. Same for kennels a properly built kennel in the bed of the truck with a solid roof and good ventilation is just fine IMHO. Now if you put the dog in there and drove cross country non stop, OK thst Im against. But for a two or three trip to the camp ground and the dogs have water, I see no issue.
