It is a very nice pit. I do like the color and know you'll enjoy the cart feature (I have a Safe with a cart). Sheriff is a good friend and won't steer you wrong. These pits are so well insulated you should be able to enjoy cooking in the winter as well. :)
Are you using the minion method? If not, light 25 briquettes in a chimney and evenly distribute them and your wood chunks across the top of the unlit coals. Might also have to better "form" the cheesy door for a better fit if it is sucking too much air around it. My experience is with a 22.5 WSM.
