I literally drove right by the entrance 2 days ago. I wasn't camping but was on the lookout for campgrounds. First of all, let me say that I think that campground is in the most beautiful place in the world. Just gorgeous. Super high elevation.
It did appear to be tight. I did see that there were several pop up campers and at least one class C down as I drove by. My suspicion is that you can unhitch and slip your tv in tight.
I would call the campground and specifically ask. I'll bet it will work.
I saw numerous airstreams traveling up and down 82 last week. A couple were vintage and polished up!
Btw, this view will be about 5 minutes from your campground. The hike at maroon bells is stunning. We saw moose, mule deer, and all sorts of amazing wildlife. I've been 3 times (not camping) and would go again tomorrow.
