So, I am picking up a truck today. Traded in my SUV, got a lower interest rate, lower payment, smart move, blah, blah, blah.... Who cares... The boy LOVES to go for a ride in the SUV. I put the windows down and he runs back and forth from window to window sniffing and his big tongue hanging out the side of his head covering most of the window frame in drool. It's illegal here in Washington to have an animal in the pickup bed if it is not tethered in. Great law in my opinion. Now, my boy is VERY protective of his peoples' stuff - so I want to make sure and get a good system that will allow him SOME freedom, but not enough to jump out in someone's face at a stoplight. He isn't aggressive unless you mad dog him, but I don't want to risk it. Sure, I can fabricate something out of Mule Tape and make some sort of attachment - I am just wondering if there is a system out there that other people have used and like for it's (usefulness, price, ease, portability, safety features ) <------ pick one. Any input that doesn't involve some wisecrack about tying him to the bumper for a little stroll or giving him enough rope to hang himself?? Thanks.
