As it turns out, the Kar Gard cannot be used on the GMC Acadia. Now, I find myself needing to return it sacrificing delivery costs and restocking fees.
Lesson learned. Investigate these purchases first.
I've been in touch with Blue Ox to see what else might work and they have nothing. The screen they show on their website is no longer manufactured. Just the replacement screen.
I'm investigating using a Roadmaster product, but not sure it'll work with Blue Ox.
Any other suggestions would be most welcome.
Thanks.
