Contact US Tower's customer service and tell them you need the Installation and 
Maintenance Instructions and also the Formal Stress Analysis Document for the 
MA-40/MARB to complete a building permit application before placing an order 
for the tower.

Most of their tubular telescoping towers are only rated at 70 mph fastest-mile 
method (old TIA RS-222-F spec) .  If your local building code requires 90 mph 
3-second average (current TIA RS-222-G), you may be out of luck.  I have an 
MA-55 and haven't had any luck getting an updated stress analysis.  (70 mph 
fastest-mile = 85 mph 3 second gust, so it's not a huge stretch to 90 mph.)

And their installation and maintenance instructions won't impress you much....

I'm in the planning phase of putting up a used US Tower MA-40.  US Tower 
keeps sending me the generic information every time I ask.  Can somebody 
please point me to a resource of where I can find the documentation that 
came with the MA-40/MARB when it was new?
