Anyone out there have experience with a Smoke Canyon Smoker Grill? The large square one with two liftable fire grates in the grill area and the side mounted smoker box. I'm new to using mine but I'm having a real hard time geting the grilling area hot enough with a fire in the smoker box. I have to build a second indirect fire in the grill area to get the cooking area hot enough. I also have to leave the fire box side door open to keep the fire burning. Love the grill but need help getting it hot enough.
