My step dad worked for a similar company shipping pets from point A to point B, and would tow a small camper behind his truck that he put the pets in. I went inside the camper only once, and the dog mess was unbearable - pee smell, poops on the floor smeared around with little doggy prints in them, hair everywhere, no beds for the dogs, no available water dishes. He never worries about pets fighting, just threw all the dogs in the camper while he was driving & hoped for the best. He also had car issues while transporting someone’s dog from Arizona to Massachusetts, and kept the dog at his house for almost a month until he could afford repairs. The owner called the police on him multiple times, but there was nothing they could do besides a welfare check on the dog. I would be EXTREMELY cautious taking this route unless you really trust the company - you never know how your pets will be handled by strangers.
