The 24x48.
Now what add/change:
- Definitely Larger casters. Maybe 8" locking.
- More robust door latches
- Insulated firebox?
- Log starter?
- 3/8" firebox?
- larger single firebox vent?
What do you think?
IMHO:
- larger wheels, yes. Anything to make it more mobile on grass or gravel.
- door latches -- never had them or used them on an offset, so I would stick with his stock versions. Just make sure the cook chamber door seals well.
- insulated FB -- no, particularly given you're in Cal. Some folks get it because they want to keep the paint nice, but hell, it's a smoker.
- log starter -- no, injects complication into your smoker and breaches the integrity of the firebox. Plus, how hard is it to start a chimney full of briquettes or lump?
- 3/8" FB -- no added benefit, it just makes your smoker heavier and harder to move. 1/4" all around is plenty.
- single FB vent that is larger -- as someone stated earlier, it can be an advantage to have multiple vents on multiple sides of the FB in windy weather.
The only other options I can think to ask about would be:
- what shelving options does he offer? Front shelf/side shelves? Removable or drop-down? Expanded metal or solid? Stainless steel? Log shelf underneath?
- ports for probe wires? How many? Are they closeable if you aren't using them?
- flat warming rack on top of the FB?
- types of closures for the FB air inlets, and for the smoke stack closure/rain cover?
- option to take the stack down to grate level?
- paint options? Some pitmakers offer options for higher temp paint.
- welded-on hooks or loops for winching it onto a pickup or trailer, or tying it down.
- does he offer a cover?
Sounds like you've made a great choice, good luck!
