I've got substantial A/C leak. The truck is pretty new. After re-charge A/C is operational probably just for 3-4 weeks. I wonder if this is a common for 3rd gen and what typical places it can be at.

When you recharged it, did the freon also contain a UV dye? Or next time you recharge it use one with a UV dye in it that you can inspect with a UV Flashlight. The leak will stand out pretty clearly.

This is a great little UV flashlight : UV Flashlight on Amazon

Seem to remember a previous post about a/c leak problem area where the rear a/c lines rub and cause a leak. May or not be your problem but easy to check. Could do a search on this site, was a somewhat common problem with certain years.

3 or 4 weeks is not acceptable at all. You need to add a small can of UV dye and check it with the light. Typical place are at fittings, around the condenser, and at the Schrader valves but the way it is leaking you won't need any obvious places to look, just make sure you check the whole system all the way to the back and you will find the leak.

It was lower right corner (front view) and it looked like a cracked welded joint to a vertical tube.
