Will work great as long as you don't have a 5th wheel hitch installed. Moving/foodservice trucks have ramp trays for ramps built under floor of trailer.

If they place it correctly, it might still work with their 5th Wheel / Gooseneck Prep Group. If they do that, and the ramps are rated correctly so they don't get bent when used for a reasonable load (something like a RZR/snowmobile, etc.), then it could be a win.
