We have a variety of shade options. We have an awning attached to the roof rack on my 4Runner and then also use a 12' tarp tent with poles. Actually, someone on here suggested the tarp tent after I found these really cool tarp/awing things from Scamp
Korea. I've found it really useful to not be limited by having to use a track on the trailer. We can move the tarp tent around to wherever we need it, drop corners as the sun sets, etc.
