Replacing Travel Trailer Door

Yes, most anything can be done with enough knowledge and money, but why?

No..

Mobile home doors typically open to the INSIDE, RV doors open to the OUTSIDE.

Mobile home doors are typically 36" wide by 80" high, RV doors 24" wide and something like 72" high..

You can buy new RV doors..

A good place to check is RV PARTS NATION they buy up RV manufacturer surplus, over runs and end of production parts..

Not sure if they ship doors but from what I understand they have a huge warehouse of them..

Depends on the size......
