Hi, I’ve got one of these racks on my T5 tow bar, the tilt allows you to fully open the rear door (mines an up and over rather than barn doors) really easy to use, light weight and really solid, holds three bikes, can hold four but not if you’ve got the spoiler fitted.
Really worth a look as it’s a great bit of kit and on offer I’ve just seen!!
Edit Having had a flam rack on a previous van I’d take the tow bar every time, for a start you don’t need to turn the bars to get the bikes to fit without touching the van or each other.
