I was looking at a 2020-2021 GMC terrain today, it's super close for later WPC's. like within half an inch, The opening is right around 29 1/2".
Afraid it'll hit the roof liner or something. any one else mess with terrains? the pinwiki stuff says it'll fit, but isn't to specific.
I have a relative with a 2014 toyota highlander and pins fit with no issues, still some room to spare.
I'll prolly just step up to the Arcadia, the opening is similar to the highlander.
