Lookout campground in NV

I am trying to obtain information about Lookout CG in Dog Valley which is in Nevada. From Lookout we could ride Peavine Mountain, the only problem is we have a 34' 5th wheel toyhauler that needs to go down these roads. The ranger I spoke to, informed me that he wouldn't do it. So my question to anyone out there is, has anyone been to Lookout and ridden at Peavine?

Any information would be helpful.
