Our 180 doesn't have the mounts on the side for the legs.  I prefer to set them on the ground anyhow. To me they just look like a head knocker fastened to the side of the trailer.  The feet have a couple holes for anchor pins supplied with the awning. I use some large spikes that are a little longer and have a sharp point instead.  They are easier to pound into hard compacted dirt.  I drive them in at an angle so the legs can't be lifted straight up by the wind.  Here's a photo of what came with the trailer.

JR is correct-the awning and the R dome are different and have different attachment  configurations-they are not interchangeable and cannot be retrofitted easily. Forest River installs one or the other at the factory as they are being built.

If your pod does not have a built in awning, then it has a keder rail which is meant for the Rdome.  Forest River sells the Rdome, as does Pahaque and Dometic.  Occasionally, there will be one for sale on this forum.

The 2017 unit will have the larger(14mm) size keder rail.

seafans, the campground is American Forks, a US Forest Service campground on the Naches Ranger District.  It's in Central Washington, up Chinook pass at the junction of the American and Bumping Rivers.

Our 2018 180 came from the factory with a Thule. The instructions say it's a Thule 5200.  It's 12 feet long.  I'm not sure how far out it extends.  It is fully extended in the photo.  I have a mesh shade tarp I tie across one end or the front if the sun is too hot.  Also the legs make a good place to tie a rope between for a clothes line for drying towels.  I couldn't find a price on the internet.
