Here's a plug for some durable hitching guides. I bought some and have not had a chance to use them but I did use some cheap telescoping ones with a ball on the end. They did do the job but were a POS and bent on the first use. I should've listened to the reviews on those.
Anyways these are really durable and made by someone you can actually speak to. Bonus points with me.
