Plenty-o-room for any sized trailer there. Not sure about the Rhino thing. There are some around there but, I can't recall seeing any of them in the actual camp.
With the way people are hurting for money right now, there might actually be a spot available for rent at McYntire now. I heard there was a couple of open ones at the end of last year but, I never saw them. I never really looked for them either though. I think it costs around 200.00 plus electricity and water to have a semi-permanent spot at McYntire park.
If you have any questions, let me or Aquaholic know. We have that place pretty wired.
