We purchased this oven to replace the existing one in our motorhome.  This is a nice oven and has the features we want, but installation was a nightmare.  The template for the rear wall was not accurate; the measurements were off and the tabs to the mounting bracket didn't match the slots in the oven.  My husband had to modify the mounting bracket to make the tabs fit into the slots of the oven. He also had to drill new holes to be able to properly position the bracket because we had a backsplash to work around.  We have not used the oven yet, but it turns on and seems to be functional.   Frigidaire needs better quality control for the mounting bracket and wall template.  Fortunately, the top template was accurate, but we learned our lesson and verified the measurements and placing ourselves.
