I did this type of work as a freshman in high school, first "real" job... years ago, but I doubt much has changed.

Most SUV and light duty truck installs were easy, we didn't use U-Haul brand but I doubt it's any different.
Please review weight ratings and manage your expectations before towing/carrying anything on the hitch. The below hitch is a class II, but etrailer lists class III for your vehicle as well.
As with all vehicle related work, it comes down to time, money, and personal interest in doing work on your vehicle. If it was me, I'd do it myself.

Decent video on the hitch install, although no mention of wiring:
