I believe this will probably help you out:

Private Sub Worksheet_Change(ByVal Target As Range)
Dim iSect As Range

Set iSect = Application.Intersect(Range(Target.Address), Range("G7:G26"))
If iSect Is Nothing Then
Exit Sub '
End If
Application.EnableEvents = False
If UCase(Trim(Target.Value)) = "AIRPORT RV" Then
'your existing macro code here
End If
Application.EnableEvents = True
End Sub

note that it goes into the Worksheet's _Change() event. Change "G7:G26" to
the exact addresses where you want to look for "Airport RV" to be entered.
That way it won't eat up too much time checking every time you change
something on the sheet - the Application.Intersect will prevent even the test
from being executed unless a change has been made in one of those cells. The
UCase(Trim(Target.Value)) strips off leading and trailing white space and
converts to all uppercase for comparison, so it is case insensitive.

I have recorded a macro that I currently run via Tools/Macro/Macros/Run. It
works fine but it is cumbersome to go throught that process. I could run it
on a toolbar button but what I really need is for it to run when a certain
word "Airport RV" is entered into a specific cell on a data entry sheet. This
cell G7:G26 is used to enter data that is moved to a specific sheet via a
vlookup formula. I have concluded that a Change Event is probibly the way to
go to activate this macro, but I have no skills to make the connection. Any
help would be appreciated.
