Like 2airishhuman said "possible Yes" You would need a really good equalizing hitch and sway control and some exceptional brakes. It would take a lot to set it up but it is doable. Now would most of us here do it. NOPE. Iv'e seen a few older Grand Cherokees on their sides because the trail was to long, But they were SOB's not AS.
IF possible I would look into something a little bigger.
May you have at least one sunny day, and a soft chair to sit in..
