Mugnaini Trailer Pizza oven
So, I've been baking for our local Farmers Market for the last two years now, in my 54x45 brick oven. I have established a great following, but am considering branching out into pizzas.
I'm considering a mobile pizza oven on a trailer and weighing the "everything included package" from companies such as Mugnaini (well over $20,000) to a home-made version, where I would build the oven on a trailer myself.
Does anybody have any suggestions one way or another? If I built my own on a trailer, it would most likely be rectangular (Alan Scott style), and the ones I see pre-assembled are usually round.
There's most likely a big difference in price and time it would take to build it vs. having it delivered "ready to go".
If I built it myself, I know there are a lot of things to consider, such as the trailer itself, good sway stability and building the oven so it doesn't crumble while being towed.
I guess one of my main questions would be if the hefty Mugnaini price tag is worth it?
After doing some more digging, I also found these guys: http://www.rockymountainwoodfireovens.com/ 
Their website isn't exactly top-notch, and their prices seem to be suspiciously low, compared to Mugnaini, but does anybody have any experience with their company?
Thanks in advance,
