The main trailer door was in bad shape.
It was actually the third door to be in bad shape. The first, the original door to the trailer, had peeled and rotted away from years of disuse and exposure to the elements thanks to both a lack of weather protection around the frame and the trailer having sat in the yard at a slight tilt for many years. The second door was a hollow-core interior door that fell apart almost immediately and never fit well into the existing frame. And the latest door was a hastily hung interior door from my house that couldn’t even latch. Gaps wide enough to fit a determined housecat existed along the top and bottom of the door frame. The new deck looked so nice that it made the door seem even worse by comparison, so it was time to give this project the attention it deserved.
The problem with mobile homes, especially older, smaller ones, is that pretty much everything is at a reduced dimension compared to normal construction. This saves space and weight, which are important for the “mobile” part of a mobile home. But it makes finding replacement materials and effecting proper repairs a little challenging. A standard rough opening for an exterior door is 82 1/2″ tall, minimum. The rough opening for the trailer is less than 79″. There are specialty mobile home catalogs and suppliers out there, but you certainly pay for the privilege of custom-fit parts. The cheapest exterior door assembly I found during my initial research was over $300 and it was pretty plain and flimsy looking. I knew Menards had steel exterior doors for around half that price, but at a standard height. Could I actually cut down a door like that?
