Newish driver? Alone I assume? Get a copy of the
Moab bible, and stay off anything harder than about the middle of his "Moderate" list. Your truck is fairly capable, but your relative inexperience could land you in trouble. While you could technically drive Hells Revenge if you stayed off the obstacles, I wouldn't if I were you. Save that kind of stuff for when you've got more experience or friends with you to help out if you get into trouble, because there are places on trails like Hells Revenge where you can REALLY get into trouble.
For easy driving and fantastic scenery, check out Long Canyon, Potash Road to Shafer Switchbacks, and Gemini Bridges (really, it's hard not to find awesome scenery on any road outside Moab, it's all stunning, pick a road and go). For a little 4WD action with little risk of trouble, you could drive out a section of the White Rim (get a permit, and combine this with Potash/Shafer for a full day of awesomeness). Bull Canyon has a couple spots you can flex out a little, and is a great drive. Chicken Corners will take most of a day, and is fairly iconic. Tower Arch in Arches is a fun trail, so is the road to Picture Frame Arch.
Get a guidebook or set of maps, pack water and snacks and warm clothes and tools/spares, and have fun.
