The formula to check for parasitic draw is to take the reserve capacity of the battery and divide it by 4. This should put you inj the 20-25ma range for most batteries. Anything more than will drain your battery.
I have a 94 Z 71 truck that I had the same problem with. I only drive it once every 5-6 weeks or so and the battery was dead every time. I checked my draw and it was right at 23ma so I added a battery cut off switch as stated above and never had a problem since.
