All I've got to do now is bite the bullet and decide whether to opt for the tow bar or go for what seem to be the more popular route of tailgate mount rack. Total cost of the former is about twice the latter but it would be worth it if it offers the better solution in the end.
It is a pain and rather fiddly getting bikes mounted and properly attached on the tailgate mounted rack, whereas it’s super easy on the Thule XT, so I would definitely agree with your conclusion
