We have a 2018 380th. We carry a 950lb. Harley limited in the garage all the time. Not sure how thick the floor is but we lag bolted that same chock in ours without a thru bolt and it works very well. We also tie down very tightly with 6 straps, 3 per side. Never has it moved in nearly 12,000 miles. Once the front end is tied down tight the bed can be lowered all the way back down. Not sure if you can do that with a wing. But the Harley is at least as long as the wing and as heavy. But it depends on which year of wing you are talking about also.
