If the front axle hit and is taking the load, the rear axle will be hanging loose and thus not pre-loaded. IMO

I think you may have this wrong, a good axle bows up in the middle so you would have to put the level on top of the axle for their to be a gap, an axle bowing down in the middle is a bent/bad axle.

It was the wrong rear axle, and no cost to me. Between forest river and the dealer, they took care of it

the front axle hits, moves upward loading the rear axle through the walking beam just as the rear tires impact whatever loaded the front axle...whats so hard to understand there??

If you place a level on the top of a good axle you will not get a gap between axle and level, you will get a rocking action, place the level on the bottom of a good axle and you will get a gap between the center of the level and the axle.
Snapper is correct.

I was thinking he meant measure the "rocking distances" (the gaps on the end of the level) which lead to my statement.

You are exactly correct and if that is what snapper meant then he is correct also, I just got confused in the wording, I apologize.

The rear axle will not be loaded until after the tire contacts the object and the spring shackle reverses from hanging down to pointing up is there going to be a load seen by the rear suspension. The difficulty is understanding how an axle can be loaded while hanging in mid air and before the shackle is reversed and also how it would be subjected to more load than the front from hitting the same object. Defies logic.

the answer is inertia. with the vehicle at speed, the front axle is still traveling upward and loading the suspension as the rear tire loads into preloaded suspension. sounds pretty logical to me.

oh...at lower speeds its worse. say you drive over a curb/sidewalk. the front axle loads the walking beam and then the rear axle hits and is basically forced to lift the coach.
