Invention 10 has numerous applications and preferred embodiments and the drawings are for purposes of illustration and should not be considered to limit the scope of the invention as such.

(11) Invention 10 may comprise a trailer main frame 20 having a top 30, bottom 40, first side 50, second side 60, a front 70, and a back 80. A first segment 90 attached to trailer main frame 20 bottom 40 first side 50 having a first aperture 100 and a second aperture 110. A second segment 120 attached to trailer main frame 20 bottom 40 second side 60 having a first aperture 130 and a second aperture 140.

(12) Invention 10 may include trailer main frame 20 first side 50 front 70 first rocker assembly 150 that may have first an end 160, a second end 170, a length 180, a top 190 and a bottom 200 that pivotally attaches to trailer main frame 20 first side 50 first aperture 100 via pivot 105.

(13) Invention 10 may include trailer main frame 20 first side 50 back 80 second rocker assembly 210 that may have a first end 220, a second end 230, a length 235, a top 240 and a bottom 245 that pivotally attaches to trailer 20 first side 50 second aperture 110 via pivot 115.

(14) Invention 10 may include trailer main frame 20 second side 60 front 70 first rocker assembly 225 that may have first end 236, a second end 246, a length 250, a top 260 and a bottom 270 that pivotally attaches to trailer main frame 20 second side 60 first aperture 130 via pivot 135.

(15) Invention 10 may include trailer main frame 20 second side 60 back 80 second rocker assembly 280 that may have first end 290, a second end 300, a length 310, a top 320 and a bottom 330 that pivotally attaches to trailer main frame 20 second side 60 second aperture 140 via pivot 145.

(16) It is contemplated that prior art air ride suspensions 340 may be utilized with numerous prior art axles 350 attached to trailer main frame 20 first side 50 front 70 first rocker assembly 150 bottom 200; trailer main frame 20 first side 50 back 80 second rocker assembly 210 bottom 245; trailer main frame 20 second side 60 front 70 first rocker assembly 225 bottom 270; and trailer main frame 20 second side 60 back 80 second rocker assembly 280 bottom 330.
