Should I just go ahead and use my 55 gallon barrel and use the 20 gallon for the feed tube. Also If I use the 55 gallon barrel and make the riser out of firebrick do I need to insulate it?

Yes that's the picture. Read this artcle about the neutral pressure plain and other relatively unknown phenomenons. Especially the part after the header "Is Your House a Better Chimney Than Your Chimney?" That might be the problem in your situation.

In all the rocket stove u-tube videos I have seen I don’t think any of them exhausted above the roof. I guess I could at least try hooking on a vertical 6 foot flue pipe on to where the flue exits the home to see if that works. That would be easy enough.
