After a few rounds of oven pulled pork I finally finished my UDS

Apologies for the image. I have no idea why between photobucket and this forum it gets rotated and cropped. It's very annoying.
This picture if from seasoning it, I also managed to get it to hold at 225 F for many hours In preparation for a Pulled pork recipe.
The question I have is, at that temperature I get almost no smoke at all. I have it running now with the meat in, this time I actually lit a couple of the wood chunks (Oak) but it has made no difference.
Any recommendations on what I might me doing wrong?
I am also a bit worried about the size of the smoker and not filling it with meat, Future plan is to add a water dish to help keep small batches moist.
