I think you have to get something like 7 yards to avoid all the charges and fees for the truck.  I guess I'll let you guys know in 2 months how it went.  My brother does concrete for a living, so I hope to cut it down to 1 month because I have a "pro" working for me.  :)

2ft wide x 4ft long x 4ft deep.... There you go !

You will need 2.4cubic yards of concrete - which means - approx 220 80lb
sacks of ready mix - Call in a cement truck for this... You'll be mixing
for 2 months by hand :)

Found it.  But now I don't understand exactly how big my hole needs to
be.

As close as I get is the info on page 9 and 10.  All I want is the
dumb thing to say "dig a hole this by this for a 40 footer."  I still 
have no idea how big of a hole I need.

The trouble with mixing your own cement is that there's *never*
really enough. Do a 4 x 4 foot pad that's 5 feet deep and you've got 
lots of concrete. If a cement truck is not an option, rent a mixer. 
Don't skimp on the plug, it's really hard to add concrete later.. :-)

That one has 7 sections and mine has 5.  I never found the specs for
base.  I'll keep looking.

Please read this and the manual from the site.  You do not have 
nearly enough concrete for the base.

I dug a hole 32 inch square by 42 inches deep yesterday for a rohn
            

  
bx tower.  It is 5 sections of 8 ft.  I just got 15 bags of 
portland cement and will add my own gravel. I was thinking about 
three 1 1/2 inch pieces of pipe stuck in the concrete to bolt the 
tower legs to.  I will thread and put couplers on the pipe at 22 
inches so they can't move.  I've got some re-bar to chuck down in 
the hole too. I've got 3 8ft ground rods and will bond with #4 
bare stranded wire.  I picked up a load of grade 8 bolts,
washers, and lock washers for bolting the tower together and to 
the pipe stubs.  Anyone have any suggestions
for me?  This is my first tower.  I will pour tomorrow afternoon.
