Someone has to be the guinea pig. Why not you?
We're talking about a truck that there's exactly, TWO, of on the road currently. They just started showing up in dealer lots a week ago. The odds of the other guy who owns this same truck having a TC, participating in this forum, AND having tried the 2018 Torklift tiedowns are slim to none.
As I see it you've got two choices.
First, buy the 2018 tiedowns and see if they fit. I haven't seen any advertising hype saying anything about "all new" so the design is almost certainly a carryover from 2018 with a few minor cosmetic changes. You've got a pretty good chance of success with this.
Second, sit around and mope until Torklift updates their information.
