ul 103 certification yes or no

[Lill Dave]

I am thinking of using the Casa 2g 100 or 110 on a mobile pizza trailer.
These ovens require a UL 103 certification for residential indoor use.
Has anyone out there used one of these on a trailer without a ul certification of this type since they are used outside.
There are spark arrestor chimney caps to fit on outside ovens that have to be ul certified but thats about all I think, I'll do more research on that on the internet after this postiog.
Are there any other ovens Forno Brovo makes or any one else that woould work well on a mobile trailer.
