Exactly what you need :))

DESCRIPTION 
This simply adds a tow hitch to some SUV models which were supposed to be able to tow trailers like the vanilla pickups in-game. The included models are: BeeJay XL, Rancher XL and Seminole. No meta edits are required for this mod, because Rockstar themselves already set up the compatible trailers for these vehicles, including the ability to tow the Anti-Aircraft trailer.

-Put the "suvtowfix" folder on update/x64/dlcpacks/
