Sorry for delay... did not notice your update...
If you look at the pic you will see I have taken 2x4's, drilled 1/4" holes, applied Construction Adhesive to both sides of the 2x4's, pushed together then pulled apart then pushed together.. keep pushing the 'all thread' thru... to keep aligned... then clamp together using the all thread nuts and washers.
After it cures overnight, use a chainsaw to give each end a slope. That makes easy to climb the ramp and fit the slope.
Our triple axle when fully supported, deflects the ramp about 1/4".
I would not have a problem with spanning more than the 8' these cover by using longer boards.
The only limitation is WEIGHT! These weigh close to 60# each. A good workout to launch and recover Mjolnir.
To cross a longer span, you could toss a couple of boards under the low spots. The deflection will stop when it touches them. Of course some of the RV stabilizer squares would work, too.
You could rig where you put more than one together by rigging a way to keep them from sliding left to right.... then place supports under the joint...
Now, the hardest part... actually aligning during the launch and recovery. I pull out until the rear is about 1-2 inches above the ground... or I see the tires starting to leave the ground (depends upon how fast your slope increases. Then align so that the tires land solidly on the outside edge and is supported by 3 of the 2x4 and will angle in the direction you are turning... as you exit, you will have to turn one way or the other.... =) Usually..
Does this make sense?
