Since the weather in RVA has decided to emulate Siberia I have only managed one cook on the Memphis, a 14 pound turkey.
Unfortunately the day I picked to cook the turkey the temperature never got above 35 and the wind was from the North at 15-20mph. With only one cook to compare the two grills I am not sure how valid my observations are but I have a few to share.
The Memphis used a lot of pellets, much more than I was expecting. Now to be fair, the Elite is a bigger grill than the Kuma but I still think the pellet usage was high for that cook even with all the wind. I had an issue with the probe during the turkey cook, the probe said the meat was done but when I checked the turkey with my trusty Thermapen the IT of the turkey was 20 degrees lower than the set temperature. The probe on my Kuma has always been dead on. I have another probe for the Memphis that I will try on the next cook to see if the problem is the probe.
I actually prefer the Kuma's grease collection system to the the Memphis so far. On the Kuma almost all the grease runs down into the drip trays making clean up very easy. It seemed that a lot of the grease from the turkey cooked on the Memphis never made into the drip trays but was on the deflector itself. The disposable aluminum drip pans for the Kuma are much smaller and much less expensive. I know a lot of guys don't use the disposable trays but I find them very convenient when it comes to clean-up.
The most puzzling thing I have noticed so far is the amount of ash beneath the Memphis deflector-I wonder if this was due to the wind. For one cook I thought it was a lot of ash. I used the same BBQ Delight pellets that I have used on the Kuma but it would take 4-5 cooks on the Kuma to generate that much ash.
I don't mean for this comparison to sound like I dislike my Memphis-it is built like a tank-the grill grates are unbelievably thick, the stainless steel is beautiful and despite its significant weight it rolls very easily (I am keeping it in my garage until I can build a patio this Spring). I just need to get more experience using it. For anyone interested in a Kuma I can readily recommend that pellet grill-it is well built, a pellet miser, has a controller that is easy to use and is very easy to clean. My brother-in-law likes it so much he wants to buy mine.
