[TowerTalk] Another Universal Tower Raising question

[douglas.snowden at med.va.gov]

I am going to put up a 90ft Universal Tower. It has the 25" base.  Being
such a
lightduty tower I was planning on using it for hanging wires that I pull up
with a
pully.  I will need to fabricate some sort of base, or buy one. My question
is
since I have no weight on the top could I pull it up with my truck by
hanging a 
pully up about 20 ft on a tree that is fairly close to it?  Scary?  Doable?
The tower
will be far from any house or property line.
