A pretty cool loop trip I would recomend for a first timer is head out of Gerlach north on Hwy 34 you will come to Soldier Meadows road. Take that north along the Playa and along the way there are two Opal Mines the second is Royal Rainbow which is pay to dig your own. This is Also part of the Emigrant Trail and you will see markers along the way made of Rail Road Iron sticking out of the ground with plaks incribed with passages from wagon train diaries.After that you will come to Mud meadows Reservoir and then Soldier meadows guest ranch, pretty cool place in the middle of nowhere. It's an old US Calvary fort with some cool rock buildings. Heading west from there is some hot springs up the Fly Canyon raod. This woul be a good place to camp. further up that road is High Rock canyon with some cool very high cliffs and some 1840's carvings in the walls, this may be closed to traffic this time of year due to Hawks nesting in the canyon. this road will take you back out to Hwy 34 which is dirt at that point and if you head north a little ways is a big petrified tree and if you go south back towards Gerlach is Leadville an old mining town with some buildings still standing.
I hope this helps but please have a Good Map take your time the roads are passable in a rig like yours but very rocky in places.
Send me a PM with phone # if you what any more info I would be happy to help.
