[RE-wrenches] "Ballasted" Ground Mount?

[robert ellison]

If you are in a snow area you will need to get it up high enough to shed the
snow, but have had customers use a rgm rack and connect the legs together
with steel connectors and pile rocks on them for ballast.
Been there for 5 years or better with no problems. Sounds like a simular
situation.
