I mounted a pivoting "D" ring (Harbor Freight) at the peak of the roof to attach triangular sail/sun shades (Costco and others). A carabiner attaches sails to D ring. Carabiner can be attached to the D ring prior to raising the roof into place or, snapped on after the roof is raised by standing on a step ladder. I used 4' X 2" ABS plastic pipes with a cap and a bolt to attach lower ends of sail/sun shades with paracord and bungees to ground spikes. The ABS pipes give added walking height under the shade "tent" that is created. I cut 4 triangular "teeth" (with a saw) into the bottom ends of the ABS pipes to keep the bases from slipping during buffeting in the breezes.
With a little practice, it is fairly quick and easy to put up and especially, take down, when a big wind comes up! I leave the peak connected and roll up the base of the triangles on each other. Put a bungee around the roll and attach it to the roof handle and the distal ends can be secured with a bungee to the bumper (if taken to the back) or the front frame (if taken forward). The triangular shapes of the shades work perfectly with the shape of the A frame and almost look like they were made for this application! Have been extremely happy with the results! Very inexpensive overall: 2 sails, D ring, ABS pipes/caps/bolts, paracord, bungees...under $75.
Only downside are the parks that don't allow spikes in the ground to protect sprinkler pipes from being punctured. In those cases, I have used the tow ball on my vehicle and a heavy picnic table to secure the ends of the sails. Not ideal but, when shade is needed, one gets creative. We have been attaching 3 short strings of "chili" lights to the edges of the sails with small binder clips placed every 18-24"...looks great at night!
