Las Vegas RV Maintenance Checklist
A self-service checklist for desert conditions: what to check every three months, what to have serviced once a year, and why the desert makes each one matter.
Three things drive most of the schedule below: sustained heat that loads cooling systems and speeds up battery wear, ultraviolet exposure that hardens seals and gaskets faster than a milder climate would, and a large day-to-night temperature swing that stresses connections and fittings through repeated expansion and contraction. Each item names which of these applies before it names what to check.
Every 3 Months
Owner-level checks. None of these need a technician, a lift, or specialized tools, just a walk around the coach with a flashlight.
Mechanical and Power
Check battery terminals and connections
Las Vegas swings from triple-digit afternoons to much cooler nights for most of the year, and that repeated expansion and contraction works terminal connections loose and speeds up corrosion faster than a milder, more stable climate would.
What to do: Look at both terminals for white or greenish buildup, confirm the connections are tight, and clean off any corrosion you find.
RV Battery Service ›Appliances and Climate
Clean the air conditioner filter and check the shroud
Desert dust loads a filter and a condenser coil in weeks rather than months, and a coil that cannot shed heat is the last thing you want discovered on the first triple-digit day of the year.
What to do: Pull the filter and wash or replace it, and look at the shroud for UV cracking or chalking.
RV Air Conditioner Repair ›Check the refrigerator vent for airflow and debris
An absorption refrigerator sheds its heat outside through a small set of coils tucked behind the exterior vent, and on a coach parked in full desert sun, that vent already has very little margin to work with before a fridge that runs fine in spring starts falling behind in July.
What to do: Confirm the outside vent is clear of dust, insects, or nesting material, and that nothing is blocking airflow behind it.
RV Refrigerator Repair ›Onboard Systems
Look over the roof membrane and skylight domes
Roof vents, skylights, and hatch domes are the most sun-exposed clear parts on the coach, and desert UV is documented to make the acrylic go brittle and craze well before a leak becomes obvious from the ground.
What to do: From the roof or with binoculars, look for chalky or hardened sealant around penetrations and for cracked or cloudy skylight and vent domes.
RV Roof Reseal ›Check window and door gaskets for brittleness
The same ultraviolet exposure that cracks a skylight dome also hardens the rubber gaskets around windows and doors, and a gasket that has gone stiff stops sealing well before it looks obviously damaged.
What to do: Press on window and door gaskets to check for stiffness or cracking, and note any dual-pane windows that have started to fog between the panes.
RV Glass Repair ›Inspect slide-out and awning seals
Slide-out wiper seals and awning fabric sit in direct desert sun for most of the day, and that heat and UV exposure dries out rubber and fabric faster than a shadier or milder climate would.
What to do: Run a hand along the slide-out wiper seals for stiffness or cracking, and check the awning fabric for brittleness or mildew.
Slide Out Wiper Seal Service ›Do a visual and smell check of the LP gas system
Heat-cycled rubber and fittings on the LP system are more prone to slow leaks over time, and a quick visual and smell check between full professional pressure tests catches an obvious problem early.
What to do: Look at visible LP lines and fittings for damage, and smell around the tank and regulator area for any gas odor.
RV LP Gas Inspection ›Sanitize the fresh water system before heavy summer use
A fresh water tank mounted on a coach that sits in desert heat warms up more than one in a mild climate, and warm, stagnant water grows bacteria faster than cooler water does.
What to do: Sanitize and flush the fresh water lines and tank before the hottest months of heavy use begin.
Fresh Water System Service ›Once a Year
These need a technician: load testing, pressure testing, and work inside a sealed system or a propane line are not owner-level tasks.
Mechanical and Power
Have the generator load tested
RV generators are serviced on run hours rather than the calendar, and a coach that barely moves can still put a generator well past due simply from running the air conditioning through a Las Vegas summer.
What to do: Have the hour meter read and the generator load tested to confirm it can actually carry the air conditioning load it will be asked for next summer.
RV Generator Repair ›Get the electrical and charging system checked
The charging system carries its heaviest load of the year during the months the air conditioning and the generator work hardest, which makes the end of a desert summer a sensible time to have it checked before the next one.
What to do: Have the batteries, converter, and charging circuit tested under load rather than just at rest.
Electrical and Charging System Check-Up ›Appliances and Climate
Schedule the refrigerator’s annual service and recall check
The refrigerator page recommends this annually for efficiency and life span, and a Las Vegas summer is exactly the season that tests an absorption fridge’s cooling capacity the hardest, so an annual check timed before summer catches a marginal unit early.
What to do: Have the burner, flue, and vents cleaned, and have the model and serial number checked against manufacturer recalls.
RV Refrigerator Repair ›Service the furnace before the first cold night
Desert nights cool off far more than the daytime heat suggests, enough that a working furnace still matters in a city known for mild winters. A unit that has sat completely idle since spring is one of the more likely things to have failed quietly, and that failure only becomes obvious the first time heat is actually needed.
What to do: Have the pilot, burner, orifice, and heat exchanger serviced before the first cold trip of the season.
RV Furnace Repair ›Have the water heater serviced
The water heater page recommends this service annually for operating safety and fuel efficiency, which holds regardless of climate, and it is a natural pairing with the other appliance services on this same seasonal pass.
What to do: Have the burner and igniter cleaned, the tank flushed of sediment, and the anode rod and pressure relief valve checked.
RV Water Heater Service ›Onboard Systems
Have the roof coating and membrane assessed
A full year of direct desert sun does more cumulative damage to a roof membrane than the same year would in a milder climate, so an annual assessment catches chalking or wear before it becomes a leak.
What to do: Have the roof surface and coating checked for chalking, thinning, or wear, separately from the quarterly visual check above.
RV Roof Coating ›Get the LP gas system professionally pressure tested
The quarterly visual and smell check above catches an obvious problem, but only a proper pressure test finds a slow leak that has not announced itself yet, and heat-cycled fittings make that check worth doing every year rather than skipping it.
What to do: Have the whole LP system pressure tested, not just the visible lines and fittings.
RV LP Gas Inspection ›Winterize before the coldest nights of the year
Las Vegas is mild by winter standards, but the same large day-to-night swing that defines the desert climate here includes occasional nights below freezing, which is enough to damage plumbing that was never protected.
What to do: Have the fresh water tank, water heater, and plumbing lines drained and protected before the coldest stretch of winter.
RV Winterization Service ›Want All of It Done in One Visit?
This checklist is meant to catch problems between professional visits, not replace one. The 45 point RV inspection covers the electrical, generator, plumbing, LP gas, appliance, and exterior systems named above in a single visit, and is a reasonable once-a-year alternative to working through the annual list one appointment at a time.
If something on this checklist turns into a symptom you cannot place, the RV appliance troubleshooter walks through the likely cause for common air conditioner, refrigerator, generator, and furnace complaints.
Found Something on the List?
Mention which checklist item turned up an issue when you call, and that context alone often points to the right diagnosis before the coach is even in the bay.
