Good advice. Another alternative.
I advocate using local independent transmission shops who set up race cars. They are generally a bit more expensive, but they know their stuff as to what works. In many cases they will have tricks to make the OEM designs more adapted to towing. Calling a local race track of any type will likely get some shop names.
Dodge/Mercedes rear end parts are notoriously expensive OEM, but those parts are exactly the same as some other more common vehicle models. You just need to find the right shop.
