Where the intervals come from

Across all 7 rig types the schedule has 296 task rows. 175 name a maker, a manual or a standard; 121 rest on community consensus (97 of them on the iRV2 forums) and say so in the Source column.

Every row carries its own source, so you can check it. The list is hand-built in the Rigly app, not generated text. Use and climate change how fast things wear, so treat each interval as a starting point.

Questions people ask

How often should an RV be serviced?

There is no single date. Some tasks run on mileage (oil, wheel bearings) and some on time (roof seals, tank flushes), so track both. For a travel trailer this schedule has 6 monthly checks, 7 every 3 months, 11 every 6 months and 13 yearly, plus 1 by mileage and 2 seasonal. Pick your rig above for the full list.

What maintenance does a travel trailer need?

A travel trailer has no engine, so the work is the running gear and the house. This schedule lists 11 chassis tasks (bearings, brakes, tires, suspension, hitch) and 29 house tasks (roof, tanks, water, propane, detectors, power). The tow vehicle has its own schedule.

How often should I repack RV wheel bearings?

Every 12,000 mi on this schedule. The note reads: “Or annually — clean, inspect, repack, new seals” Source: etrailer / community. Follow your axle maker's manual if it says different.

How often should I inspect the RV roof?

Every 3 months for the seams and every penetration, and yearly for a full reseal (“Self-leveling on top, non-level on sides”). Source: Dicor / RVIA.

How often should I replace RV tires?

By age as well as tread. For trailers the schedule's note reads: “ST tires: replace at 3–5 yr regardless of tread” For a gas Class A it reads: “Replace at 6–7 yr regardless of tread — check DOT date” The date code is on the sidewall. Check pressure monthly.

When should I winterize an RV?

Before the first freeze. This schedule puts winterizing at Oct–Nov and de-winterizing at Mar–May, which suits much of the US; move the window to match your climate.

Can I use this instead of my owner's manual?

No. These are starting points. Each row names where it came from, and rows marked community consensus are what experienced owners agree on, not a maker's rule. Your owner's manual and the parts makers' guides win. For brakes, propane and tires, have a qualified tech check anything you are not sure of.

Do I need the Rigly app to use this?

No. The tables and the PDFs are free to read and print. The Rigly app puts the same kind of schedule on your phone and reminds you by mileage and date. It works offline and stores your records on the phone.

Want it to remind you?

Rigly keeps your records on your phone, works without signal, and turns these intervals into reminders by mileage and date. Free for one rig.
