Welcome from all of us here in middle Georgia.
I've been cookin' outside for a few years and recently became a pelletizer with a GMG Daniel Boone. I am greatly encouraged to know you used yours for so long.
GMG are pretty decent pellet grills. I had my issues, of course, but my local dealer had the best customer service. I bought it in 2012. I had to change out the controller, and fire rod, but it was still under warranty. After the warranty expired the low pellet sensor went during an overnight cook, and there was a constant beeping. I ended up just cutting the sensor wire to stop the beeping. After that my hand held remote stopped showing me the current temp of the grill. They have mad many improvements since then with WI-FI, stainless steel guts, and such. I bought the stainless steel heat deflector, and 2 piece grease tray to replace the rusted/warped steel parts before I gave it to our daughter. I left it up to her if she wants to buy the retro fit WI-FI controller that comes with a new probe, and pellet sensor. I also had a Don Godke Downdraft on it to try to even out the temp at the grates. I had to rearrange the three piece heat shields, but I think the downdraft helped. Some like them, some don't. In my opinion, I think the GMG grills are still a step above the Traegers, but they all can produce some good eats.
