Just traded in my Chubby for an Extended Party.
All you need is two or three lit briquettes added to the basket, right front corner. I just add one starter cube tucked under the right front. Leave door/vents open for the first 20/30 minutes then close door and leave vents open until you reach 50 deg below your target. Close the left vent completely and right vent leave open maybe 1/2 inch. Your draft should be wide open and NEVER needs closing. Always adjust temp from lower vents. I add water in the beginning. The above method I was getting about 8 hours at 225, 6 hours at 275.
I added a couple 16/16" tiles under the basket to lift it up but I didn't like the space it took up above the basket for wood chunks. I just bought some welders gloves to help lift out the basket.
