Do you have a rear mobile home door available that measures 34.5 by 74 ? that is the outer screw in frame measurement. Doesn't have to be exact measurement or any particular design. And a rough price please. Thant you.

They have plenty of doors that size.

I don't have the exact answer you're looking for but I am aware that mobile home doors range from 200 to 280 depending on what you're looking for which means window or no Window and Door I have found it cheaper to buy an exterior house door it will fit just require some more framing. Regular house door at Lowe's runs 144 that is one steel door with frame no windows
