Just thought I would update this thread with some pics of the Atera Forza M fitment for anyone looking into carriers. We bought one having seen the posts above from
@Bubble21 and
@Shoggy
Preference for the Forza was because it is foldable (we have limited storage space) and was a bit lighter than some. Not as light as the Uebler i21 but they were about an extra £150 and couldn't justify that.
So folded up it looks like this

You drop it onto the towball but don't clamp it up yet and then unfold it to something that looks like this.

Pushing down the bar under the number plate holder allows the whole unit to pivot down

At this setting the tailgate just catches on the catches that release the upright, you could squeeze these in to let it pass but actually you don't have too (see next text block)

The Atera has an adjustable restraint strap that allows you to alter the degree of tilt from about 75deg to 90deg. All you do is undo the retaining nut on the strap and move it from position 1 below to position 2!

The rack will then drop down further and the tailgate will clear no problems.

Next step, loading bikes. Pics below show it with 1 bike loaded and then the rack folded flat. Clearance isn't an issue.

Can't add any more pictures so will continue the post in part 2
