I love the mobile oven - it is extremely well built. I've probably made a close to three thousand pizzas in it since March (I've been busy!!). It holds temp really well. The guys did a great job with it.
As far as my dough...it is nothing top secret - just the way the VPN guys trained me...water (out of the Dallas tap...no mysterious filtration systems), fresh yeast, 00 flour (I've been using Molino Spadoni PZ2), and sea salt. I've had to do a lot of tweaking on the standard ratios with the crazy hot summer we've had hear (much less yeast and a bit more salt). I stay pretty close to the 60% hydration...it may go a bit higher if I get sloppy with the water. I don't use much yeast at all...for this past weekend I used 10k/11lbs of flour and only 9g of fresh yeast and 140g of sea salt. water goes in first, then salt, mix with whisk, then yeast, mix with whisk, 50% of flour, mix on low 5 mins, rest for 15 mins, rest of flour, mix on low for 12 mins, rest on marble slab covered with wet towel for an hour, ball into 250-265g balls, 24 hr rise in the fridge. That's what has worked for the Dallas summer - this year at least. I've done a 7 hr room temp rise with good results for "same day dough" but because I'm usually making them for events for paying customers, I like to make it the night before - that way if it messes up I can use same day dough as a fallback.
I also run my oven hot - try to maintain 900 throughout - 60-90 second pizzas. 4 at a time is tough to juggle. More pics from this past weekend below. Very last of the hatch chiles though...
