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....

Subject: [TowerTalk] ma-40 documentation
To: "Tower and HF antenna construction topics."
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?
