Choosing direction!

[MrB]

Hey there everyone! I have been digging through pages and pages on every WFO site there is. I have been trying to familiarize myself with the basics of building an oven before I started asking a bunch of questions that have allready been answered somewhere.

I plan on building my oven on a trailer I already own. It is a single torsion axle 6x12. It hauls three 4x4 4wheelers so I assume it will hold my oven.

I am planning an oven very similar to the one's that Allen built off of a wood frame with the rebar sitting in slots in the wood ties.

or... buying a refractory modular from Forno. Still using the idea for the base from Allen's. I like the idea of the wood frame base because I can remove it from my trailer if need be.
Has anyone else built a oven that can be removed from a trailer?

Which way would y'all go with it? Modular or home built?

Please put me in the right direction so I can start building!! I am addicted allready!

Any input to get me started will be much appreciated!
