I have been hanging my hammocks off of the Jeep and the truck but I wanted something that I could leave up, in place without having to move the vehicles. So I got one of these.

It works well with the Hennesys, the ENO and the Grand Trunk.

But hanging a tarp on it just doesn't work. I got some bugs to work out on that. When all is set up, it looks good, but when ya get in the hammock, there is enough "give" in the rails to loosen up the tarps.

I need to come up some extentions to be able to hang the tarps higher. And I am gonna try some bungi or innertubes to keep the tarps taunt after I get in.
