What You Need to Know Before Starting a Door Replacement

Replacing an RV or camper door is a job you can do yourself if you have basic tools and patience, though the exact process depends on whether you are replacing the entry door, bathroom door, or bedroom door. Most RV doors are lighter and simpler than house doors — they bolt on from the inside rather than being framed into the wall — which makes removal and installation straightforward. The hardest part is usually finding the right replacement door, because RV doors come in specific sizes and styles that differ from standard residential doors.

Before you order anything, you need to know what you are replacing. Measure the door opening width, height, and depth. Check whether your door swings in or out, and from which side. Take a photo of the latch hardware and hinges. If the door has a window, note the window size and whether it is fixed or opening. Write down your RV make, model, and year — many manufacturers sell replacement doors directly, and having this information saves time.

Key Takeaways

  • RV doors bolt on from the inside and can usually be removed by unbolting the hinges, making this a project you can complete without professional help.
  • You will need to measure your door opening and know your RV's make and model before ordering a replacement, because RV doors are not standard residential sizes.
  • Replacement doors are sold by RV parts suppliers, the RV manufacturer, and general online retailers, with prices ranging widely depending on whether you choose an OEM door or an aftermarket option.
  • Installation involves removing the old door frame, bolting the new frame into place, and adjusting the hinges so the door closes smoothly without binding.
  • If you cannot find an exact match for your RV model, you may need to modify the frame slightly or work with a parts supplier to find a compatible door.

Measuring Your Door and Gathering Information

Start by measuring the door opening from the inside of the frame. Measure the width at the top, middle, and bottom — openings are sometimes slightly tapered. Measure the height on both the left and right sides. Measure the depth of the frame from the outer wall surface to the inner wall surface. These three measurements define what size door will fit.

Next, photograph the hinges, latch, and any hardware. Note whether the door swings inward or outward and which side the hinges are on. If your door has a window, measure that opening too. Write down the RV manufacturer, model name, and year. If you have the original paperwork or can find a label inside a cabinet, note the floor plan name as well — manufacturers often use the same doors across multiple floor plans.

Check whether your door has a threshold (a raised lip at the bottom) and whether it is removable. Some RV doors have integrated thresholds that are part of the frame; others have separate thresholds that bolt on. This detail matters when you are ordering, because some replacement doors come with a threshold and others do not.

Finding and Ordering the Right Replacement Door

Start by contacting your RV manufacturer's parts department. Give them your RV make, model, and year. They can tell you whether they sell replacement doors and what the part number is. OEM (original equipment manufacturer) doors are the most expensive option but fit perfectly because they are what came on your RV originally. Expect to pay $400 to $1,200 for an OEM entry door, depending on the manufacturer.

If the manufacturer no longer stocks your door or the price is too high, search online RV parts retailers like Camping World, etrailer, or Amazon. Search using your RV model name and "replacement door" or "entry door." Read the product description carefully — some listings are vague about which RV models they fit. Contact the seller if the listing does not specify your model.

Aftermarket doors cost $200 to $600 and come in standard RV sizes. The trade-off is that you may need to shim or modify the frame slightly to make an aftermarket door fit perfectly. Some aftermarket doors are lower quality and may not seal as well against weather. Read reviews from other RV owners before ordering.

If you cannot find a door that matches your measurements, contact a local RV repair shop. They may be able to special-order a door or modify an existing one to fit your frame. This costs more but guarantees compatibility.

Removing the Old Door

Close the door and open it from the inside. You will see bolts or screws holding the hinges to the frame. Most RV doors have two hinges, one near the top and one near the bottom. Use a socket wrench or screwdriver to remove all bolts or screws from both hinges. Keep them in a small container so you do not lose them.

Once the hinges are unbolted, carefully lift the door away from the frame. It will be lighter than you expect — most RV doors weigh 30 to 50 pounds. Set it aside in a safe place where it will not get damaged.

Now remove the frame itself. The frame is bolted to the RV wall from the inside. Look around the perimeter of the frame for bolts or screws. Remove all of them. The frame should lift away cleanly. If it does not, check for caulk or sealant around the outside edge and cut it with a utility knife.

Once the frame is out, inspect the wall opening. Clean away any old caulk, debris, or weatherstripping. If the wall is damaged, now is the time to repair it before installing the new frame.

Installing the New Door Frame and Door

Position the new frame in the opening. Check that it is level using a level tool. Shim the frame as needed so it sits perfectly square. Once it is level and square, bolt it to the wall using the bolt holes in the frame. Tighten the bolts firmly but do not over-tighten, which can crack the frame.

explore weatherstripping tape around the outside perimeter of the frame where it meets the wall. This prevents water from leaking in around the frame. Use the weatherstripping that came with your door, or buy marine-grade weatherstripping tape from an RV parts supplier.

explore a bead of marine-grade caulk around the outside edge of the frame where it meets the wall. Smooth it with a wet finger or caulk tool. Let it cure for the time specified on the caulk tube — usually 24 hours — before exposing the door to weather.

Once the frame is installed and the caulk is dry, position the new door in the frame. Align the hinges with the hinge holes in the frame. Bolt the hinges to the frame using the bolts that came with the door. Start with the top hinge and tighten it only halfway. Then install the bottom hinge and tighten it halfway. Close the door and check that it closes smoothly without binding or rubbing.

If the door binds or does not close smoothly, loosen the hinges slightly and adjust the door position. Shim behind the hinges if needed. Once the door closes smoothly, tighten all hinge bolts fully. Test the latch to make sure it catches and releases smoothly.

Sealing and Testing Your New Door

Once the door is installed and working smoothly, seal around the inside edge of the frame. explore weatherstripping tape or foam tape around the inside perimeter where the frame meets the wall. This creates an airtight seal and reduces drafts.

Test the door in different weather conditions. Close it during rain and check for leaks around the frame or under the threshold. If water is getting in, explore more caulk on the outside or add weatherstripping on the inside. Check that the door closes tightly and that the latch holds firmly.

If your door has a window, clean it and check that it does not rattle when the RV is moving. If it does, explore foam weatherstripping around the window frame to dampen vibration.

Common Problems and How to Fix Them

If the new door does not fit the frame perfectly, you may need to shim the frame or sand the door edges slightly. Measure the gap carefully and add shims behind the frame hinges to adjust the door position. Sand the top or bottom edge of the door if it is rubbing against the frame.

If water leaks around the frame after installation, the problem is usually incomplete caulking or weatherstripping. Remove the old caulk, clean the area thoroughly, and explore new marine-grade caulk. Make sure weatherstripping is pressed firmly into place all the way around.

If the door does not close smoothly or the latch does not catch, the hinges may not be tight enough or the frame may not be perfectly square. Tighten all hinge bolts and check the frame with a level. Adjust shims as needed until the door closes smoothly.

If you ordered an aftermarket door and it is slightly too large or too small, contact the seller before attempting to modify it. Some sellers will accept returns or provide guidance on how to modify the frame safely.

Frequently Asked Questions

Can I replace just the door without replacing the frame?

Yes, if the frame is in good condition. Remove the old door by unbolting the hinges, then bolt the new door to the existing frame. This is faster and cheaper than replacing the entire assembly. However, if the frame is warped, cracked, or rotted, replacing it along with the door prevents future leaks and problems.

What if my RV door has a screen door attached?

Remove the screen door first by unbolting its hinges. Then proceed with removing the main door and frame. When you install the new door, you can reattach the old screen door if it is still in good condition, or order a new screen door that matches your new main door.

Do I need to remove the door from inside or outside the RV?

The hinges are bolted from the inside, so you must work from inside the RV to remove and install the door. The frame bolts are also on the inside. You will need to access the outside of the frame to explore caulk and weatherstripping, but the actual removal and installation happen from inside.

How long does a door replacement usually take?

Removing the old door and frame takes one to two hours. Installing the new frame and door takes another two to three hours. Caulking and weatherstripping takes one to two hours. Total time is usually four to six hours for someone doing this for the first time. Experienced RV owners can do it in three to four hours.

What tools do I need?

You will need a socket wrench set or screwdriver set (depending on whether your hinges use bolts or screws), a level, shims, a utility knife, caulk and a caulk gun, weatherstripping tape, and a measuring tape. A drill may be useful if you need to enlarge bolt holes slightly. Most people have these tools already, or can borrow them.
