I've got a Comp Cam 260 (so-called RV cam) installed in my 360, but I don't remember all the spec's (engine was rebuilt 13 -14 years ago). My driving plans were similar to yours - mild offroad, some mud, mostly street (jeep was my daily driver for 22 years, now daughter is driving it). I wanted the the power to come in "off idle" and didn't need high RPM stuff - didn't plan to race it.
I helped rebuild a 360 for a friend - he used a Comp Cam 268. Had more of a "lopey" idle. And his gas mileage wasn't just "AMC V8" bad, it was really bad.
