I think you'll be very impressed with the RT590.

Slowmo,
That grub looks tasty! And your kit and deck look great!
I'm not convinced, though, by your "heat rises" dismissal of the Silverbac's double wall construction below the grates. I'm not a specialist in thermodynamics, but I know enough to remember that convected heat (which goes up and out the smoke stack at the rate set by the fan drawing in cooler air from outside the grill) and radiant heat (which travels in all directions from its source and is either absorbed or reflected) behave differently enough to explain a legitimate engineering decision to double-wall a grill near its primary source of radiant heat.
Again, I'm no expert in thermodynamics, but as I see it all pellet grills lose about the same amount of convected heat (the "heat rises" kind) based on the speed of the fan and regardless of insulation, steel thickness, etc., but lose radiant heat to varying degrees depending on insulation, material reflectivity and thickness, etc.
Hence, while little can be done about the "heat rises" kind of heat in any unit that constantly adds cool air from outside and allows smoke to escape, quite a bit can be done about radiant heat.
Anyway, I respectfully don't think the Silverbac's engineering (or marketing) is as unsound as you suggest.
Of course it's just opinions unless someone with both a Stampede and a Silverbac load them both with the same amount of pellets, set them at the same temp in the same environment and see which one runs out of pellets first.
(No one will do it though because real science would put the squash on at least half of social media, and what would be the fun in that? Ha!)
Bingo. The temperature delta between the wall of the grill and the outside air is going to drive heat transfer. The lower half of the Grilla runs cooler than any other pellet grill I've had the opportunity to use (save my Father in-laws Timberline, which is also insulated in that area), which means it is losing less heat through skin losses. They're all still losing heat to skin loss from the top, and the argument was "why insulate anything if you're not going to insulate the top, because HEAT RISES." It's partially true, but it neglects the fact that some-insulation still prevents more heat loss than none-insulation. An additional benefit for those of us with littles running around the yard, the bottom of the barrel stays cool enough to not cause a severe burn particularly when running at moderate temps.
The fact is that both of these grills are great, and a better value for the money than the Traeger offerings. Some people will be turned off by bullhorns and the RecTec culture. Others will be turned off by the more swing = more smoke argument (the Alpha controller allows you to choose what you want). When it came time to spend my money I couldn't stand the bull aesthetic and the way people get attacked for negative experiences with RecTec drove me elsewhere. Grilla offered a number of features I liked and at a lower price point, so that's what I got.
This is way off the original topic, but maybe it's worth inserting.
The LG900 has a better burn pot design than do most of the imports, but like the Yoder with the same design, there is no heat deflector between the flame and the grease pan which thus has to do double duty. This causes a radiant heat hot spot above the flame. The Outlaw pellet smokers use a pellet delivery/fire pot system very similar to that of the Yoders and LGs, but they do two things differently, resulting in more even heat across the cook surface. First, they add a heat deflector between the flame and the grease pan. Second, they vent the unit with a long slit at the back rather that using a smoke stack at the far end.
I've been looking around and I can't find any other pellet cooker that combines the Yoder/LG burn pot configuration with a separate heat deflector and a long slit rather than a stack on the end.
I'm going to drive over to the Outlaw shop Friday, meet the owner/designer, kick the tires a bit, and report back when I get the chance.
Doesn't the LG900 have around a $1900.00 price tag?
The LG900 sells for $700 at Costco and is shipped from Amazon for $900. In that price range it appears to have the best system for smoke generation--better than Rec Tec, Grilla Grills, Traeger--but probably suffers from a hot spot over an inadequately shielded burn pot.
Oh, and I may have been unclear earlier about how it compares to the more expensive Outlaw. They share, or essentially share, the superior pellet burn system and vent system but are different in that the Outlaw has an additional layer of steel deflecting heat from the flames for more even radiant heat.
Edit: Does anybody know why an automatic link to Rec Tec gets inserted when I post to this forum but not one to Grilla Grills, Traeger, Outlaw, etc? Is this forum a front for Rec Tec?
I see that now. Thanks.
I see that now. Thanks.
I was beginning to wonder, though, given the almost cult-like non-objectivity I see from time to time in support of that brand over others.
That sort of thing, and the fact that the main dish served up in online debates is red herring, reminds why I usually don't spend any time on BBQ forums--and convinces me again to just not do it.
That site is just a click through referral revenue generator, not a real review site. They all follow the same format. Faked reviews that summarize Amazon reviews and a bunch of links to resellers.So many votes for Silverbac and just two for Traeger? (mine included)
I've come across this Traeger review and I would go for it... Or is it just a commercial trap?

That said, I'm one of the people who thinks that Traeger is a premium priced brand that is in reality just average. Lots of competition does the same or better for less money.
Much is made of statements by Grilla about features of their grill but you have one of the Recteq guys who is an ex car salesman talking about stuff that don't matter. Running the burn pot over with a truck for example. You could probably do the same with a Grilla burn pot or some of the other companies. The fact that you can do that don't matter. He also says you need a PID controller. No, you don't. Is the fact that the temps will swing a big deal? No, it is not. The whole Recteq presentation by those two can be awkward to be polite about it yet Grilla is singled out about the insulation. Just an example of someone seeing what they want to and not seeing what they don't want to.
