I can only speak for Pitmaker as that is the only vertical I have experience with. This thing is a beast. According to the computer on my excavator, the Vault weighs 978 pounds naked. That's a pretty solid cooker for sure. If you are looking to buy a vertical that is insulated out the gills, and that will easily last a life time, you owe it to yourself to at least look at the Pitmaker line up. I purchased mine back in March. At that time Pitmaker was no doubt the heaviest duty units on the market with Spicewine and Humphreys right behind them. But as with most thing you cant go wrong with any of the above named. I just liked the reverse flow design and massive weight of the Pitmaker more than I did the others. Good luck my friend. And if you change your mind and decide to go with a offset, then be sure to give Shirley down in Tuscaloosa a look. You will be more than impressed with his line up.
