your issue has less to do with power, gears, or transmission, than with physics.

you have less traction pushing a load up a hill than you have pulling it. Spinning tires means you have enough power, just not enough traction.

Seems this would make it worse with the weight now on the front wheels with a lighter rear end. The tires would still spin. Just a thought

Say what? Can you elaborate on how you came to this conclusion please?

Thanks!

This is exactly the cause. Weight transfer going up hill. Weight is transferred off the driving wheels, thus reducing traction. If your tires are spinning, you have more than enough power.

This is how my neighbor does it and keep the WDH hooked up and it transfers more weight to the rear.

Again, please elaborate. Some of the tow vehicle's weight is transferred off the rear tires, but some of the trailers weight is transferred TO the rear tires. I'd wager that the net loss/gain of tractive force on the rear tires is pretty minimal.

Then explain the wheelspin in reverse versus forward. Weight transfer.
