I use mine with tailgate down anytime I haul mine in Dodge Dakota. The real wheels sit on tailgate with my toolbox in back of truck. It is legal to do so, just not legal if not hauling anything (or at least that was what I was told by Highway Patrol). I even got stopped recently by a city police and no problem with tailgate down. He did have a problem with my speed however. I recently got a Louisanna Guard Dog <a href="http://www.laguarddog.com/" target="_blank">http://www.laguarddog.com/</a> and love it. You can hook up and secure in seconds and is very secure. No more straps that can break and crash through your windshield. Go to their wibsite and look at them. I got the Slack-n-ator version for about $15 more at a totol of $159. Sounds kinda pricey but how much is a rear window when you have to break quickly and strap breaks. Not to mention the time to strap down and unstrap which is a pain. It also can be used to secure and lock your ramps from theft with locks you can also purchase from them or elsewhere. Theirs are all keyed alike which is what sets theirs apart from others.
