I have lived in the tri-Cities for many years. I have always being a guy facinated with off roading. I currently have a honda crf250r 4 stroke dirt bike. I always go to Juniper Dunes on my days off and use it. I got it last year and have being practicing using it. I have gone riding with some friends but they are all much better than me.
I also have my 2004 Nissan Titan. I dont know if there are any places around here to have some fun off roading with it. I guess Juniper but any other places. I definitely wouldnt like crashing it or soemthing like that. but would love to go have some fun with it. Any one know of a really good place for a beginner to start?
Time for some pictures.
You would have the same issue I have with your rig. Size. There are, according to the crew, almost no trails around here that won't turn a fullsize in to something that looks like a "squeezed tube of toothpaste" (Old Green) 
I do fine out at Juniper with my F150, but I like sand 
Spend some time in the runs sections of the site to get a feel for what the runs are like...And enjoy the site
