i've been looking at all of them. backwoods, stumps, pitmaker, superior, spicewine and so on. but quality & size vs price makes me lean towards pitmaker.
if i were to find a good unit used at a good price i would take any of them. but if i am going to shell out for a new unit i want it to be good.
from my research and this is hearsay!!!!
the problem with the stumps is inconsistent heat in the chamber you could have 20 deg difference from left to right and from top to bottom, it's something to do with the fire box being on the side and the way the heat travels.
the backwoods is good but most people find the build quality to lack and uses thinner metal.
i see the biggest complaint about vertical water smokers being that the waterpans rot out. the pitmaker makes the waterpan out of stainless to combat the problem.
please this is by no means a bashing session i am just pointing out what i have found on the internet. and i would absolutely buy any brand of them if the deal were good enough!!!
