No Witt, taking the back tail beam screws out really did nothing or maybe allowed 1/6th" movement.
Jay, you're right! I looked at a stock USH FEF-3 and it is held from the bottom not through the stack. I'm pretty sure I've looked everywhere above the pony truck and found no screws, but once I get done with the sand hatches I'll go back the TTT.
