Are you going to set it yourself, or get someone to do it for you...? We have a 2019 GC that I set up myself. Its not that difficult if you're handy with tools. eTrailer.com has some good installation videos of the process.
To answer your original question, there is nothing special other than putting the xfer case in neutral and connecting all the equipment in order to tow.
Some folks have had issues with the "death wobble" with earlier models, but I have never experienced it with ours. We have the Overland model with the air suspension. I always make sure the suspension is pumped up to regular ride height and the power steering set to sport mode before turning everything off before pulling out.
