bouncy floors in my zeppelin

[dmgtools]

I own a 2006 zeppelin z291 and from what i read online, this line is notorius for having a floor that flexes quite a bit. anyone out there have experience with bracing the floor on their rig? my plan is to run 2x4 or 2x6 joists between the frame rails. Thoughts, concerns, ideas? thanks in advance

We also have a 291, put 3/4 treated plywood between the frame rails used screws to hold up temperarily, had 2 inch angle iron with flat 1/4 x 2 x 4 pate welded to ends with two holes drilled in each end. the total length of the angle and plates is the same as the width between the frame. Used jack to push the metal up under the plywood tight and used self tapping screws to through the drilled holes to the frame. same idea as 2x6s but wont rot. spray painted everything black.
