I'll trade you your next snowfall for my next tropical storm if you want.
Here's a thought experiment that hopefully will make it easier to understand what's going on with trailer weight and balance.
A 200 lb dad makes his 100 lb kid a teeter totter. For the sake of making the numbers easy let's say the teeter is a 16 foot board and assume its weight is negligible.
Now, the kid sits on the left end of the teeter and lifts his feet. What happens? The rule is that both the forces and moments (torques) on the teeter have to end up netting out to zero for it to be stationary and stable.
So, the kid lifting his feet is applying a 100lb x 8ft = 800ft-lb torque due to gravity to the teeter. His weight forces it to swing counter clockwise till his feet touch the ground again. He will end up with 100 lbs of force pushing up on his feet to counteract the 100 lbs from gravity forcing it down. Net torque (moment) = 0 so nothing is rotating.
Total net force on the teeter also has to be zero or it will either lift in the air or dig itself into the ground. Since the teeter plus kid weigh 100 lbs and the ground is pushing up on his feet with 100 lb force to counteract the torque, the forces are balanced too, and so there is zero force required on the teeter pivot.
Now, let's say the dad gets on. Being a savvy guy on teeters, he sits 4 feet out from the pivot and lifts his feet. What happens?
He is now imposing a clockwise torque of 200 lbs x 4 ft = 800 ft-lb on the teeter due to gravity. This exactly balances the kids 800 ft-lb counterclockwise torque so the kid can lift his feet and the teeter doesn't rotate.
But what about the forces? There is now 300 lbs gravity force on the teeter from the weight of the two ppl on it, but neither one's feet are touching. So, were does the force get countered? By the pivot of course, which now has to push up with 300 lbs force. So the force on the pivot just went from zero to 300 lbs. even though we only added 200 lbs of weight.
This is whats going on with the rPod when you add weight aft (the dad) to try to reduce the hitch weight (the kid). The load on the pivot (the axle) goes up by the added weight plus the reduced weight on the hitch.
That's why its not such a great idea to add a lot of weight aft to reduce hitch weight. Its kinda self defeating at some point because it can quickly overload the axle.
It also increases the "polar moment of inertia" which is a measure of a vehicle's resistance to turning/sway. That's why the best handling sports cars are mid engine designs, by keeping most of the weight near the middle of the car its easier to get it to turn. By having lots of weight out at the far ends its both harder to get a trailer to start swaying but more importantly its harder to get it to stop swaying once it starts.
So, I think the approaches to reduce hitch weight (in my order of preference) are
1) leave stuff at home
2) move stuff from the front of the trailer to in front of the tow vehicle rear axle (the most lightly loaded axle on the rig is the front axle of the TV).
3) move stuff from the front of the trailer nearer to but in front of the trailer axle.
4) move stuff from the front of the trailer to behind the trailer axle.
