Flex in chasis/frame - calling at 10 footers...

Here are my chasis/trailer specs.
Perimeter and 1st inner-most crossmember - 2x2x1/8 tube steel
Stringers - 2x2x1/8 angle on 2' centers
Tonge/Straight - 3x3x1/8" tube steel
A-frame members - 2x2x1/8 angle
Tonge from front of 1st crossmember to center of ball - 43"
Axle position - 46" from rear
The frame looks great
...BUT, as it sits in this picture...if you push down on the tongue, you can see the whole frame flex "up"
and/or bend - more than what I wound have expected... is 2x2x1/8" tube enough for the perimeter, should I start over or will the "box", a/k/a TD body, keep this from happening.? should I add stiffeners somewhere, extend a piece back to the 3rd stringer, etc
.... I thought this was more than stout enough and maybe it is for 8' but maybe not for 10'...for the first time on this forum I wonder if I "under"-built;
What did everyone else use for frame on 5x10 TD?... I'm more than willing to go buy all new steel (heavier) and start over....but as you can imagaine, I'd rather not... but I do NOT want to compromise... it looks so good, really, and the wheels and tires are gonna look great... I'll post pictures of those tomorrow after it's rolling, if I don't rebuild.
