Now that you have confirmed your height and the exterior wall size, yes, definitely can have the doors you want. As you see Sylvia and Gram has them and so do I.
LOL, it must be a women thing for these doors. I have a large (for a MH anyways) foyer entrance, this is where we had the sliders removed and patio doors installed. Love the amount of light and the view, makes the area so much brighter.
As mentioned in one of the previous post there may be some creative trim work to do after the install, but nothing that you can not over come.
Gram, your dining room looks great, it's been awhile since I have been to your site. The color came out great, love the white accents, what a real pop!
