Side slope, what to expect vs Rubicon w/ 5.5" lift?

[Alan06SUT]

I am going offraoding with a doctor buddy of mine this weekend. He's got a rubicon w/ a 5.5" rubicon express lift. It should be a fun trip because he, like me, doesnt seem to give a phuk when it comes to testing limits. I will push the envelope but do so without being an idiot. I have taken the h2 (adv pkg stock tires) off road 4 times since i bought it in Sept, but have never really tested it on a side slope. I have a lev-o-guage and want to take it to the limit if presented the opportunity.

At what angle should I take it to on a side slope? I will load the heavy stuff in the bottom of the bed (no stuff on roof).

Also where will I be able to show him up? Or will he leave me in the dust? We are going to NC so it will be rocks w/ mud and some narrow, paint scratching trails I imagine.

Thanks guys.
