I can't tell from the photo, but have to ask, do you have oversized tires or a suspension arrangement that raises the TV vehicle bed above the normal range? Also, my understanding from Reese and Blue Ox is that the distance from the RV overhang to the TV bed rails is supposed to be between 6 & 8 inches. Another concern is dragging the rear of the fiver. Even with level, I've scraped the bottom several times simply due to the uneven layout of a campsite pad. From your picture, that should be a big concern.
