> I read on timberlinetrails.net that Campers, Motorhomes, Travel Trailers and other types of specialty overnight setups are not allowed in the Portal parking area. Do you know if this restiction is just for the portal parking area right in front of the trailhead or does it include the overflow parking area just below the trailhead parking? It would be nice to use our cabover at Horseshoe Meadow and then just park it in the overflow during our time on the mountain.

I hope somebody else can better answer this...

I am pretty sure that is only due to the limited parking space -- cars park side-by-side, and long vehicles would be a problem.

It is quite likely you can find a parking spot, either in the overflow, or parallel parked along the road.
