Thank you John for the nice comments
To answer Robyn's ( and others ) question on the floor, I have not had any issues with any oven's floor, however I brought it up to the FGM owner's attention. He told me that he bought and took over FGM about 7 years ago and for what I understood the oven Robyn got was ordered by the the distributor in CA about 10 years ago.
The new owner is committed to providing the best quality and has had some molds redone, back when he first arrived, as they didn't meet the quality standards.
In any case, should an oven be defective, the warranty will cover such issue.
Regarding the question for the oven mounted on wheels, attached is a picture of my latest creation. This is a 700 C Raised, mounted on a cart and fitted with multiple options such as a tool rack, an ash box and landing area/counter top in front of the oven. Such installation can be done for any residential oven and I am working on doing the same thing for a business who wants to move their oven inside during the winter and then outside when the weather allows.
