Think of this trailer like a wheelbarrow. The load is close to the wheels in both cases. This trailer is like a wheelbarrow with really long handles. The long-handled wheelbarrow is much easier to lift than a standard wheelbarrow, because you have more leverage and the load stays close to the wheels. Yes, the extended handles do weigh something, but the added leverage decreases the force needed to lift it. Imagine the extreme case. Put a 200-foot-long hitch on this trailer and you could probably lift the trailer by hand.

The center of gravity does change though by changing the length of the tongue. It increases the distance between hitch and center of axles as well as the overall length. When the overall length changes but load area does not change, it changes the center of gravity.
I'll just have to disagree. In this discussion we're speaking about Rentento's trailer. The weight of the tongue extension is insignificant compared to the trailer. The mass of the trailer doesn't change so how could the center of gravity also known as the balance point change significantly? The trailer will still balance at the same point.
We can agree to disagree. Here's the theory behind it though. Let me know what you think.
Think of it as leverage. You have the same pole that we talked about yesterday. 10' long with a fixed point 2' from the end. At the other end we place a scale. Now we set a 100# weight in the dead center from fixed point to the scale. That is 4' from fixed point and 4' from scale. So we have 50# on the scale and 50# at the fixed point. Do we agree?
Now move that weight toward the fixed point 2'. So now we have 100# on the bar 2' from the fixed point and 6' from the scale. What is the weight on the scale now?
Edited to add: The trailer will still balance at the same point (or close enough). The difference is the mass of the trailer is 18" further from the hitch in the truck.
Tres... I've come to agree with your result but not because of your illustration. You're moving the weight. Retento's trailer is stock except for the extended tongue. So the distribution of weight is the same for the modified and stock trailer between the nose and tail. The extended tongue provides additional "leverage?" on the trailer reducing the hitch weight.

That's funny. I realized after I posted it my example was flawed. I should have extended the bar rather than moving the weight. The result is the same, but it doesn't explain as well. Glad I could convince you that you were right though!

OK, OK, you wize guyz....
Two Gore extended neck/tongue horse trailers left a farm traveling in opposite directions at the same rate. One trailer traveled 372 miles in 1 1/2 hrs more than the time it took the other trailer to travel 279 miles. Find the speed of the horse trailers....

They never did beat the Exiss that traveled 573.2493 miles at an average speed of 154.7308 MPH. Of course the roof blew off, all the welds failed and the remaining pieces arrived on a flat bed truck.
