I have a GMG Jim Bowie with remote and I love it. I had a bad controller card right out of the box, but my dealer and the great CS at GMG got me a new controller before the following weekend. After that I spend some time getting it dialed in and seasoned. Now it is running full steam ahead and I have less than a 20 degree difference across the grate. I get a constant TBS with the pellets that I use (Bear Mtn from C&C).
I have done steaks, a ball tip roast, a few tri-tips, chicken thighs, pastrami and a few pizzas on this guy and no issues.
I did 1 mod to it to turn the low pellet alarm off and on. Next up is to convert it to run off of DC/Solar and a remote that can text me when the pellets get low.
Side note: When dialing the grill in both the Daniel Boone and the Jim Bowie have unique characteristics. Some remove the baffles, some need them there, or like me I needed the right baffle in but plug the holes in it.
