As for the spelling errors, it's not always the person's mistake - too often people are posting using tablets and cell phones. These will automatically change words or auto-spell words to the devices preference. For example, we're you going to do that? - my phone added the apostrophe to my typed were. I'm a bit anal and tend to catch those, but many people don't. So, I've learned to not worry about the spelling when it's a casual setting like this.
And if we're going to complain about trailer vs.camper, then we need to discuss the differences between RV Park vs. campground and RVing vs. camping.
