drjjj,
This set up has worked well for me for several years. Will not blow over in the wind and is simple to make, take apart and store. I have stored the base supports in the sewer hose bay along with a couple of hoses. Now it is stored in the storage bay up front in a plastic bin with other things. The gutter sections are in the front bay also.
The supports are made from 1/2" PVC and fittings along with simple vinyl gutter sections.
You simply use as many supports and gutter sections as you need.
