Should I replace my Toyota HiLux with a Ford Ranger or Mazda BT50?

I have a 2008 Toyota HiLux SR5 diesel with 300,000km and I’m looking at upgrading. I looked at the new-model HiLux, then someone suggested I look at the Ford Ranger and I also looked at the Mazda BT-50. I use the vehicle for dogs, and tow a dog trailer occasionally, I also do tracking comps with the dogs, so I could be in paddocks. I also have puppy bars set up in the HiLux. What would your suggestions be, please?
