Thanks everyone for the responses and suggestions. I did order the Currie JK baseplate and the Demco Commander tow bar (with the Demco Blue Ox adapter clevis, which definitely fits better!) and also got the CoolTech wiring harness. Now to set aside some time to get the baseplate and wiring harness installed and tested.
I liked the idea of keeping the cutting and modifying of the Jeep frame/bumper to a minimum, so the Currie baseplate made a lot of sense to me. The last part of the solution is what to get for a toad braking system.
