Great looking setup!!
If it were me I'd scrap that Reese setup and go with either the Reese Dual Cam or the Equalizer Brand WD hitch. ($500-$600)
If you have the money you might even want to look into the Hensley or ProPride ($2000-$3000?)
IMHO looking at that TT it's probably right at the edge of the capabilities of that F150 (the suspension not the engine).
So I'd invest in a good quality WD/Sway hitch and IMHO you will be happy you did.
The difference between the Equalizer brand hitch I have now and the Reese style I used to have (just like the one you have) is huge.
