Ours is 25 feet long...I would not see a problem getting yours in there. We did not experience anything negative entering the park. They have a nice sized parking area at the visitor center. From the visiter to the campground, the roads are nicely paved and well marked. We saw large rigs and several huge Class A's. I was really impressed with this campground. On another note....absolutely "do not" leave food outside and when cooking inside, leave the windows shut. There are black bears in this area and they warn all campers. They recently had a bear do significant damage to a travel trailer...took off a good bit of the sides trying to get into the camper. They shut down the park for several weeks after the incident. When we were there, we did not see anything and cooked all our food inside and kept the trash inside also. Try looking up that incident online....they posted a picture of that travel trailer. This place is really nice....if you get our spot, you'd swear you were the only ones there! Hope this helps....safe travels!!
