Using the Thule Motion XT XXL Cargo Box on a 2017 GMC Acadia Limited
Question:
Will a thule motion xt xxl fit my vehicle with any aftermarket crossbars? I have factory crossbars and I believe the largest one that will fit is the thule motion xt xl. Can you please confirm?

The Thule Motion XT XXL, part # TH629907 can fit onto most factory crossbars, thanks to its incredibly flexible clamps. These are shared across the Motion cargo box line.
However, the spread of your crossbars will need to be measured. You'll measure from the center of the front bar to the center of the rear bar. All boxes will have a certain range of crossbar spreads that they will fit.
Another concern is with how well it lets your rear hatch operate. You can verify the fit prior to purchase with a simple measurement. If you can adjust your crossbars, move them all the way forward. Then, measure the distance from the center of the front bar to the line where your rear hatch meets your roof. This distance is the front clearance your vehicle has, and is how manufacturers fit and size crossbars.
For the Thule Motion XT XXL, the box requires a crossbar spread of 23-5/8 inches to 36-7/8 inches, and a front clearance of at least 55 inches.
For the Thule Motion XT XL, part # TH629807 requires the same 23-5/8 to 36-7/8 inch spread, and a front clearance of 51-1/4 inches.
If you have a particularly large spread, I recommend looking at the Yakima SkyBox 18, part # Y07336. This box fits a spread of up to 42 inches, and requires 57 inches of front clearance for hatch operation. This box will be a little smaller than the Motion XT XL, but can adapt to a wider bar spread.
I've included video reviews of both lines of cargo boxes, so you can get a better idea of their performance.
