After making an ATV and 2 ATV crates, in order to affix the crates to the ATV storage rack I need to drop the crate and then pick it up - now that it is in my hand - I can equip it on the ATV (there are no written signs on the ATV, just a blue outline of a crate on the storage rack). There needs to be instructions on equiping the crates - or better yet a hand menu that gives the option to equip the crates from your intentory
