I used 10' sections of PVC, and it made a hoop house about 4' tall. I got SOOOO tired of bending over and walking at the same time!!!
PVC is so lightweight that the next PVC hoop house I make will use 1" 20'pipe (even if I have to use a connector on two 10' pipes). That will give me a house in which I can stand up, but that is still lightweight.
I have also considered 3/4" 20' rebar as the basis for a non-moving hoophouse (see this site for greenhouses, where I got the idea: http://www.northerngreenhouse.com/ideas/how_to/rebar.htm
Personally, I love my horse-panel chunnel, even though it is not movable. I know it is 100% completely dog/raccoon/hawk/possum/etc. predator-proof (only rats and snakes might be problems)
