Welcome to the forums... plenty of "weight police" on here and based on your answer above, which I liked, you might not be driven off this forum. Unlike most 8-10 percent tongue weight is enough for me so yes I would try it with what you have. That said, that's a lot of trailer for your SuperCrew... the tail may wag the dog when being passed by a 18 wheeler. The other problem is trailers have a way of growing over time.
If you have room to move your 1000 lbs around you can adjust your tongue weight.
