good luck

So maybe it's just low of R134,

Maybe so. But before you go add some more, take it to someone who as a set of real A/C gauges that can check the high-side and low-side pressures while the truck is running.
It could be cutting out because the pressure is too high because of an obstruction. I had this happen on my LTD. Low-side would gradually come down, but the high side would get up over 450psi (dangerous) if I remember correctly.

Anyway!
No one here could tell me how often the compressor clicks, is it every 10 sec?
I just don't need to waste money at the shop if nothing is wrong with the AC.
How do you tell when the AC compressor is working correctly? Mine is cooling just fine, the clicking sound is what I'm not sure?? Maybe if someone explains to me in more details how often you hear the AC switching when its working properly, then I can really know for sure if its working ol right.

I know I hear mine fairly often, about once every ten-fifteen seconds at crusing speeds. It is fully charged and the pressures are perfect. And it's cold even on the hottest of days, it usually puts out air in the 36-40 degree farenheit range.
I've heard of others taking two-hour interstate trips and never having the compressor cut out.
