Sweet so ..
. let me understand your redneck physics. .... Going over the bump will increase the weight..... Because apparently it cause greater force....
Lets look at that fancy formula from our friend above : f = m a. Now which one is changed? M or a?

At static equilibrium (ie driving down a perfectly level road with super awesome smooth pavement) the vertical force exerted on the hitch (F gravity) is equal to F=ma. m being the mass of the trailer that is distributed to the ***** and a being gravitational acceleration.
When you hit a bump there is an additional force (F accel) exerted on the hitch equal to F=ma. m being the same mass as previously mentioned but a being the acceleration derived from the change in vertical position.
The force exerted on the hitch, is the vector sum of (F accel) and (F gravity).
COOL i don't even like caboose.. you are making me actually like this guys patience..
personally i wanna hit you over the head with a stick till it breaks just to say
'Thats why."
The weight of your load is not your tongue weight. it depends on where your load is in relation to the axles of the trailer, the number of axles, and the height of the load in relation to the hitch if not more and more things. Think about how guys with pickup trucks pull 3000 pound boats.... the tongue weight is not 3000 pounds.
The acceleration that is relevant here is the vertical acceleration of the object. On a smooth road, the force on the tongue is relatively stable since there isn't much vertical acceleration. Going over a bump, the vertical acceleration of the bike and carrier will rapidly increase, which increases the force on the tongue.
Go stick a 2x2 in the receiver and stand on it. It'll support your weight. But it'll probably break if you jump up and down on it.
cool - drive down a flat road with your hand between the hitch and the tounge. That pain you will experience is the tounge weight from your trailer. When you hit a dip or bump in the road, your bones breaking in your hand are the result of the force on the tounge of the trailer changing.
As an aside, I'd imagine the tounge ratings for a hitch are static weights, and have the additional dynamic forces factored in.
Ohhh right, I'd forgotten this had gone on so long! hahaha, I thought it was about the trailer in a bag or something still, but had gone on to hitch receivers.
As Buck says, though... in his aside... I'd imagine they have those things factored in, and you don't have to get out your protractor and calculator to know what your 450 pound load weighs in a negative vertical acceleration.
