I have a straight mount for my spare, only in my one driveway does it just scuff pulling out if I go to fast. It also doesn't help that the springs on the Yukon are sagged, but that should be expected with almost 200K on them. As far as reviews, take them with a grain of salt. Without know what type of trailer it is it's hard to judge how low it would be on your trailer. The one on my Speedster trail is only 8" off the ground, so as you can tell it's hard to judge, this extra angled one could net me more clearance than what I have now. I might have to upgrade and then put the straight on on my utility trailer, oh wait, then I'd need to actually get a spare for the utility trailer.
