The new visitor center is open, just off highway 160. RVs and towed vehicles can go to the Morefield campground if you have a reservation. "Small" RVs can drive through the park - check with the rangers for any size limits. I've seen "small" class C RVs inside the park. I've also seen tag axle tour buses, but they have commercial authorization and restricted parking spaces.
Wolf Creek Pass? Yeah, we live at the base of the pass, and travel it frequently. Drive safe and take your time. Last week, a trucker lost control, and there were 44,000 pounds of "mashed" potatoes all over the pass. Fortunately, he escaped with no injuries.
