Default oil filter leak?

I got my oil changed a few weeks ago, and noticed a oil drip around the filter. I brought the truck back, and they put another oil filter on. 2 weeks later same case, and again they put on a new filter. Now I am on my 3rd filter and it is still dripping. Not fast just a little drip after I drive for a while and it gets hot. Anybody had this issue before?

Just a couple simple things to check:
After you get it put on, have you tried tightening to see if it will go on more? Shouldn't need to as they usually tighten them too much.
What is the filter number? Can you see it. Are they putting the correct one on?
Again, they should see and verify, but is the gasket coming off when the old is removed? Since it's been done 3 times, I would assume so.

yes, it is very tight as I have tried to tighten them more and they wont. as far as filter number I will get back to you when it is not flooding outside..... and yes the old gasket is off.

Hey I am having the same problem - did it myself the second two times to be sure it was right, still dripping- love the truck but worried about the thing blowing the filter on the highway - wondering if it was overtightened if it would warp the housing or if it is cold weather related??
