Any help is really appreciated.
I recently bought the Smoke Hollow Pro 44 from Sam's and plan to use it for the first time this weekend. For the price I thought it was worth giving it a shot.
While putting it together I removed the hose that came with it and replaced it with the Bayou Classic M5HPR-1 which includes a needle valve. I also put Fireblack 1/2 x 1/8 black gasket around the 2 doors only because I read the smoke may leak out the door a bit. Depending on how it holds smoke I may also line where the top and bottom units come together with Rutland Stove Gasket Cement Black.
With the needle valve in place I was able to easily hold 140 without worry of the flame going out but I don't really plan on needing to go that low. I've been using the AMNTS for a couple years now and plan to use that in the SH as well. Using only one burner (with the AMNTS above the other unused burner) and with the valve limiting the flame, I don't see how it can really burn through gas any faster than anything else that's putting out the same flame. It's possible that because of the heat/smoke leakage in the door that more gas may have been needed to maintain temps but with the gasket in place I can't see that as being an issue.
If you don't plan on purchasing right away I'll let you know how the SH performs and how much LP it uses if you'd like. I don't have a lot of time to smoke between the kids' soccer and basketball games so I'm only planning on doing a couple tri-tips which should only take 1.5-2 hours so it may not be a good indication of fuel consumption.
Sorry it took so long to get back to you. I've smoked ribs, pastrami, tri-tip so far and it's worked great. It's almost too easy with the heat (gas) and smoke (AMNTS) being separate. With the mods it can hold steady at 175 if you ever wanted to go and can get too hot to where it fuses shut a flue (yes, I did that on the initial seasoning - oops). The temp was so high it really burned down the gasket so it isn't holding the smoke as well as it could have otherwise but I'm still able to get a good amount of thin blue smoke coming out the stack.
The 12" AMNTS fits perfectly where the removed chip box would go. I also used the 18" AMNTS and put it higher up on the lowest rack near the door and that worked fine as well.
All in all, I'd buy it again and do the same mods. It works well and is worth the money IMO. With a Maverick or 2 in there it really is set it and forget it.
Hope that helps even though it's so late.
