Question 1

How often should an RV roof be inspected and resealed?

Accepted Answer

Every 3–4 months (quarterly-class), plus before and after any long trip. Roof seams, vents, and edge trim are the #1 source of RV water damage. Small cracks are cheap; the water damage behind them isn't. Source: Dicor roof-sealant care guidance (inspect roughly every 6 months at minimum, more often in harsh sun/climate); general RV roof-maintenance guides. Always confirm the exact interval in your owner's manual.

Question 2

How often should an RV generator's oil be changed?

Accepted Answer

Every 100–150 running hours, or once a year — whichever comes first (varies by model). Generators are small engines that work hard in heat. Old oil is the fastest way to shorten a generator's life, even if it barely gets used. Source: Cummins Onan RV generator owner's-manual guidance, as summarized across RV-generator service guides. Always confirm the exact interval in your owner's manual.

Question 3

How often does an Aqua-Hot hydronic heating system need service?

Accepted Answer

Once a year (diesel-fired units). Aqua-Hot systems heat your water and your living space. An annual service catches a worn nozzle or dirty combustion chamber before it leaves you without heat or hot water. Source: Aqua-Hot Systems, Inc. official annual-maintenance guidance. Always confirm the exact interval in your owner's manual.

Question 4

How often should I check the hydraulic fluid in my RV's leveling jacks?

Accepted Answer

Check level every 3–6 months; check fluid condition about once a year. Cory's own words: leveling jacks are the thing owners forget to check — low or dirty hydraulic fluid (it's often the same ATF that's in an automatic transmission) can mean a jack that won't hold, right when you need it to. Source: Lippert hydraulic-leveling-system maintenance guidance. Always confirm the exact interval in your owner's manual.

Question 5

How often should an RV water heater anode rod be replaced?

Accepted Answer

Once a year (Suburban-brand steel tanks); Atwood/Dometic aluminum tanks don't use an anode. The anode rod sacrifices itself to corrosion so your steel water-heater tank doesn't. Once it's used up, the tank starts corroding instead. Source: Suburban water-heater anode-rod guidance, as summarized in RV-maintenance how-to guides. Always confirm the exact interval in your owner's manual.

Question 6

How often should RV slide-out seals be inspected and lubricated?

Accepted Answer

Every 6 months. Dry, cracked slide seals are how water and dust get in, and they're one of the cheapest things on this whole list to maintain. Source: Manufacturer RV-maintenance-checklist guidance (Lippert, Winnebago). Always confirm the exact interval in your owner's manual.

Question 7

How often should an RV slide-out's motor and gears be lubricated?

Accepted Answer

Once a year. The gears and rails that move a slide in and out take real mechanical strain every time you set up camp — a little grease now is cheaper than a slide that won't move. Source: Lippert RV-maintenance-checklist guidance. Always confirm the exact interval in your owner's manual.

Question 8

How often should a towable RV's wheel bearings be repacked?

Accepted Answer

Every 12 months or 12,000 miles, whichever comes first. This is a time-based job, not just a mileage one — condensation can pit the bearing races even while a trailer sits parked between trips. Source: Dexter Axle / Lippert (LCI) manufacturer maintenance specifications. Always confirm the exact interval in your owner's manual.

Question 9

How often should RV tires be replaced, even if the tread still looks good?

Accepted Answer

Check the manufacture date every year; plan to replace at 5–7 years regardless of tread. RV tires often age out before they wear out — rigs sit between trips, so sun and time crack the rubber long before the tread wears down. Tread depth alone isn't the test. Source: Michelin and other major tire-manufacturer age-based replacement guidance. Always confirm the exact interval in your owner's manual.

Question 10

How often should RV batteries be checked and maintained?

Accepted Answer

Check water level/terminals every 3 months (flooded lead-acid); load-test once a year. A battery that quietly loses capacity over the off-season is one of the most common 'why won't anything turn on' surprises at the start of a trip. Source: General RV-manufacturer maintenance-checklist guidance (Winnebago, Blue Compass RV). Always confirm the exact interval in your owner's manual.

Question 11

How often should RV brakes be inspected?

Accepted Answer

Once a year, by a qualified technician. Whether it's a motorized RV's hydraulic or air brakes, or a towable's electric brakes, this is safety equipment — and towable brake magnets and wiring are easy to forget since they're out of sight. Source: General RV-manufacturer maintenance-checklist guidance. Always confirm the exact interval in your owner's manual.

Question 12

How often should an RV furnace be serviced?

Accepted Answer

Once a year, ideally before the season you'll need it. A furnace that's never been looked at is the last thing you want to discover isn't working on a cold night. Source: General RV-manufacturer maintenance-checklist guidance. Always confirm the exact interval in your owner's manual.

Question 13

How often should an RV roof air conditioner be serviced?

Accepted Answer

Clean/replace filter a few times a season; full inspection once a year. A clogged filter makes the whole unit work harder — that's how a slow leak in the roof gasket around it goes unnoticed the longest. Source: General RV-manufacturer maintenance-checklist guidance. Always confirm the exact interval in your owner's manual.

Question 14

How often should an RV's sanitation system be maintained?

Accepted Answer

Rinse/flush tanks after every trip; inspect valves and seals twice a year. Tank valves and seals are inexpensive parts that are miserable to deal with when they fail — a twice-yearly look keeps small leaks from becoming a bigger repair. Source: General RV-manufacturer maintenance-checklist guidance. Always confirm the exact interval in your owner's manual.

Question 15

How often should an RV's propane system be tested for leaks?

Accepted Answer

At least once a year (or every 5,000 miles). Propane runs your fridge, furnace, water heater, and stove — a slow leak is rare, but it's the kind of thing you only want to find on a schedule, not by accident. Source: General RV-manufacturer maintenance-checklist guidance. Always confirm the exact interval in your owner's manual.

Question 16

How often should RV smoke and carbon monoxide detectors be tested?

Accepted Answer

Test every 6 months; replace batteries annually; replace the units themselves every 5–10 years. These are the cheapest, least glamorous items on this whole list — and the ones you most want working the one time they matter. Source: General RV-manufacturer and fire-safety maintenance-checklist guidance. Always confirm the exact interval in your owner's manual.

Question 17

How often should an RV awning be inspected and lubricated?

Accepted Answer

Once a year. A dry, unlubricated awning arm is how a small squeak becomes a torn awning fabric on a windy afternoon. Source: General RV-manufacturer maintenance-checklist guidance. Always confirm the exact interval in your owner's manual.

Question 18

How often should RV roof vents and fans be checked?

Accepted Answer

Once a year. Vent and fan housings sit right at a roof penetration — the same spot that's already the #1 water-intrusion risk on the whole rig. Source: General RV-manufacturer maintenance-checklist guidance. Always confirm the exact interval in your owner's manual.

Question 19

How often should a motorized RV's chassis be lubricated?

Accepted Answer

Once a year, or per your chassis manufacturer's service schedule. A motorhome rides on a truck or bus chassis underneath the RV part — that chassis has its own manufacturer service schedule, separate from the house systems. Source: General motorhome chassis-manufacturer service guidance. Always confirm the exact interval in your owner's manual.

Question 20

How often should an RV's fresh water system be sanitized or winterized?

Accepted Answer

Sanitize once a season; winterize before freezing temps, de-winterize before the season starts. A fresh-water system that sits unsanitized or unprotected from a freeze is how a $20 job turns into cracked fittings and a cracked water pump. Source: General RV-manufacturer maintenance-checklist guidance. Always confirm the exact interval in your owner's manual.
