How often should I service RV wheel bearings?

Sat, 20 Jun 2026 14:29:50 +0000

I just bought a used travel trailer, and I’m trying to get a better handle on routine maintenance before we head out on our first long trip. I keep seeing different advice on how often RV wheel bearings should be serviced, and I’m not sure whether I should go by mileage, time, or just wait until I hear a problem. For those who’ve owned RVs for a while, how often do you service your wheel bearings, and what signs tell you it’s time sooner?

When should I reseal RV roof seams after travel?

Sat, 20 Jun 2026 14:29:50 +0000

I just finished a long trip in my RV and I’m wondering when I should reseal the roof seams after all that travel. I can see a few spots that look a little dry, but I’m not sure if I should reseal right away or wait until I do a full roof inspection and cleanup. For people who’ve dealt with this before, how do you know it’s time to reseal, and what signs do you look for?

Answered: Which cleaner is safe for RV rubber roof care?

Sat, 20 Jun 2026 14:29:50 +0000

For most RV rubber roofs, the safest choice is usually a cleaner that is made specifically for RV roofs and is labeled safe for EPDM or TPO, depending on what your roof is made of. Those products are designed to clean dirt, pollen, road grime, and light oxidation without being too harsh on the membrane. If you do not know your roof type yet, check the RV manual or look for a label from the manufacturer before buying anything. That matters because EPDM and TPO can have slightly different care recommendations.

A mild soap-and-water mix is often the gentlest option for routine washing. A bucket of warm water with a small amount of non-abrasive dish soap or RV wash can handle basic cleaning without stripping the roof. Use a soft brush or sponge, rinse well, and avoid scrubbing hard in one spot. If the roof is only dusty or has light dirt, there is usually no need to jump straight to strong chemicals.

What you want to avoid are petroleum-based cleaners, strong solvents, harsh degreasers, bleach-heavy mixes, and abrasive scrub pads. Those can dry out the rubber, discolor the roof, or damage sealants around vents, seams, and accessories. Even if a product says it cleans well, it is not worth using if the label does not clearly say it is safe for rubber roofs. I would also be cautious with pressure washers. A little too much pressure can lift seams, force water into cracks, or damage the finish.

If you are dealing with mildew, black streaks, or tree sap, choose a cleaner that specifically says it is safe for the membrane and test a small hidden area first. Roof edges and lap sealant can react differently than the main surface, so a small test spot is smart. After cleaning, rinse thoroughly and inspect the roof while you are up there. This is the best time to catch cracked sealant, loose trim, or punctures before they turn into leaks.

A good routine is to clean the roof a few times a year, especially after storage, heavy pollen season, or a long trip. Keeping it reasonably clean helps you spot problems early, and that is often more valuable than trying to make it look brand new every time. If you want the simplest answer, go with a rubber-roof-safe RV cleaner or a mild soap solution, then avoid anything harsh or petroleum-based.

Answered: How do I repair a loose RV cabinet hinge properly?

Sat, 20 Jun 2026 14:29:50 +0000

A loose RV cabinet hinge is usually a small problem that turns into a bigger one if you ignore it, especially because the constant vibration from travel keeps working the screws loose. The first thing I would do is open the cabinet and inspect both the hinge and the wood around it. If the screws are simply backing out, try tightening them by hand with the correct screwdriver rather than a power driver. That alone sometimes fixes it, but if the screw keeps spinning or won’t bite, the hole is probably stripped.

If the screw hole is stripped, do not just shove in a bigger screw unless you know there is enough wood to support it. A better repair is usually to remove the hinge, clean out the old hole, and fill it with glued wooden toothpicks, bamboo skewers, or a hardwood dowel trimmed to fit. Wood glue helps the filler bond to the cabinet frame. After it dries, cut it flush, then reinstall the hinge with the original screw size or a screw only slightly larger if the wood around it is still solid. In most RV cabinets, the material is thin plywood or particle board, so you want to avoid splitting it with oversized screws.

If the hinge plate itself is bent, cracked, or worn, replace the hinge rather than trying to force it back into shape. Cabinet hinges in RVs are often inexpensive, and a fresh hinge can save a lot of frustration. While you have it off, check whether the door is pulling crooked because the hinge screws on the door side are loose too. Sometimes both sides need attention. If the door has dropped a lot, mark the hinge position before removing it so you can line it back up correctly.

For cabinets mounted into very soft or damaged wood, a more durable fix is to use threaded inserts or small machine screws with backing hardware if the design allows it. That is not always practical in an RV cabinet, but it is stronger than relying on the same worn-out holes forever. If the cabinet is a high-use one, like over the sink or near the entry, it is worth doing the repair properly rather than a quick patch.

A couple of practical tips: do not overtighten, because that can strip the hole faster or crack the face frame. Use a hand screwdriver for the final snugging so you can feel resistance. Also, check the other hinges on the same door while you are there, because one loose hinge can make the others work harder. If the cabinet keeps loosening even after repair, a small dab of removable thread locker on the screw threads can help on metal-to-metal parts, but it is usually not needed for wood screws.
