There's enough room to pull a vehicle off to the side by the gate on Heimer road.  This is an easy trek with a very gradual elevation change.  The trail is a nice groomed gravel road that leads all the way to the summit. 

 If you keep veering right at all the forks in the road, evenutally you will end up at the summit on a nice wide gravel plot perfect for setting up a decent station.  Not a whole lot of shade to be had here, unless you climb off the path.
