I think it's a good looking grill... Pricing is pretty reasonable... only time will tell if it's newer octagon design really gives more space inside or not....
Yoder pricing is such, that it's almost pointless to compare a Stampede to any of the Yoders...
If you want to compare Q450 to it, that's a bit more reasonable... but then, Q450's main grate is just 24x19", compared to 29.75x19.75" of the Stampede...
In terms of the Stampedes headroom.. that 9"... compare that to any more traditional 20" barrel design, which yields about 9.5" of headroom at the very center of the grill... With the Stampede, that loss of 1/2" apparently is only at the very center of the grate, on either side of that lip ( that's apparently there to give that long horizontal surface some additional support )... one could argue that there's more room in the Stampede than any 20" barrel shaped design... FYI I fit a 18 pound turkey in a Traeger Junior and it's only got about 7.5" of headroom right at the center, so I doubt there'd be a problem getting a 20 pound turkey in a Stampede... heck you could probably get two of them in there.
With Wifi, all it's stainless and $900 price ( shipped )... I am betting that the Stampede will become Rec Tec's biggest seller.
