Hi Knuckles,
Here is my Hubba-Hubba tent/fly/ground tarp on my Nitto front rack from Rivendell:
I use two straps from REI to hold it in place. The poles are with my air mattress in the pole tube on the Arkel rear pannier. The rack isn't light, or cheap, but it is made and works well. My sleeping bag is strapped to the top of the rear rack.
