I have been using the 20' silver version, and their drive on holder for a 
couple years with good results. The mast sections, aluminum, are thick, 
and once you plant the vehicle on the holder, it's not going any place.
We use it to hold a microwave dish for certain sites to prove we can connect.
For a couple weeks after hurricane Charley, it sat under a Sheriff's 
department RV carrying critical data in our network.
