The most important thing you need is tow points front and rear.. you need to be able to get pulled out in either direction.
The second most important thing you'll need are competent spotters. Someone who knows the limitations of a Jeep, and ow your Jeep is set up.
I would like to see you have a tow strap, a fire extinguisher, a flash light, and a first aid kit. The rest are luxury's.. CB (Very important later trust me), and a winch (also very important later)
Not sure about how well the 35 will hold up, but as stated above.. stay off of the Skinny pedal if you are in a precarious situation....
