Did quite a bit of research before we got the GMG Daniel Boone. Have had it over 3 years and still love it. Also recently got the new GMG Davy Crockett for the motorhome.
Use it year round 3 or 4 times a week (covered patio in Oregon).
Love the remote control (option), the food probe, the digital temp control. Etc. Etc.
Tech support is great. I've called with questions and always got a real person and excellent info.
The previous comment about soot (without getting too far into it) is something that will be cured when they call customer service.
It will Grill food (hot and fast) up to 500 degrees. It will BBQ and smoke food (low and slow) down to 150 degrees. The pellet cooker is a different breed and takes a bit of a learning curve but in no time you'll be making great food. Cook meats, veggies, and desserts.
A great web site for all things pellet grill is pelletheads.com, lots and lots of info.
I have no affiliation with GMG or pelletheads, just a very satisfied cusotmer.
