Replacing an RV entry door can be a challenging task because of the nature of the vehicle. Most manufacturers do not make standard door sizes, and this is what makes it hard to procure one. However, if you do manage to get one that fits your RV, it is not very hard to go about changing it.
Step 1 - Remove the Old Door
You need to remove the old door by carefully dismantling it from the frame. Do this by removing all screws one by one. As most RV doors are built as a single unit, this particular step may take you longer, but it will be worth it in the end.
Step 2 - Use Putty Tape
Once the old door is out of the way, secure the door frame to the wall using at least one layer of putty tape.
Step 3 - Screw In Bolts
Now, all that is left is to bolt in the door using a manual nutdriver or power drill, and use a plastic scraper to remove excess tape. Bolting the new door in is easy and should not take you very long.
Step 4 - Check Door's Swing
If you did everything right, then the door should be able to swing freely without any inhibition. If the door size was wrong or if there was a problem with the frame, then you may need to re-do the previous steps.
