Trailer tracking
If the distance between your trailer axle centerline and your rear axle centerline is the same as your wheelbase (front to rear centerline on your tow vehicle) then your trailer will track identically to the tow vehicle. Since trailers aren't normally designed for specific vehicles the tongues are the length to place the weight where it's 'pretty good' not to help with tracking.
Since you're building to suit and for a particular vehicle, you could (if you so choose) both balance and track the trailer to the rat.
Does that make sense?

I am interested to see how well it tows also. Right wrong or in different, I used mainly the same tongue length as my big trailer. Trailer tongues in usually all seem to be about the same length no matter how big the trailer, that is usually around 40" to the ball from the deck, which is about half the width of your car.
As for axle placement I wanted it to be heavier in the front than the rear. Most of your weight rides in the back on a teardrop because of the cooler, chairs, in my case battery and inverter, and what not. The front won't have much in it, maybe some clothes. For this reason I put the axle at 3/4 the length of the trailer. With all the junk in the back it should still have a decent amount of tongue weight, but not too much. Since this is mainly to be towed with the rat, and the hitch almost hits the back axle, it will not have much leverage on the rat.
That was my logic anyway. Thoughts?
