There’s a meaningful difference between someone who lives in their RV for a two-week road trip and someone who calls it home year-round. The weekend camper can afford to ignore a slow-draining gray tank or a slightly soft roof seal for one more trip. The long-term resident cannot.
Full-time and long-term RV living is genuinely comfortable and cost-effective — but only when the rig is maintained with the same regularity that a homeowner applies to a house. A $40 tube of lap sealant applied on a Saturday afternoon is a very different conversation than a $2,000 delaminated wall from water intrusion that sat unaddressed for a season.
This checklist is built for long-term residents — people living in their RVs for months or years at parks like Diamond Valley RV Park in San Jacinto — who want a practical, recurring maintenance schedule to protect their investment and keep daily life running smoothly.
Stationary living changes what wears first. When an RV is parked in one position for months, UV exposure and environmental factors differ significantly from a rig in regular travel. Tires develop flat spots from stationary loading. Roof seals that would be “good enough” for one trip per year can fail under sustained UV exposure in Southern California’s high-UV climate.
Hookup life adds its own variables. Full hookup living at a long-term park means your water lines are under continuous pressure, your electrical system draws from shore power daily, and your sewer connection is in constant use. Each creates wear patterns that occasional campers never encounter.
The Metropolitan Water District manages Diamond Valley Lake and publishes seasonal trail conditions on their site. A vehicle/parking fee applies at dvmarina.com; no advance reservation is needed for trail access alone. DVRP residents are approximately 5 minutes from the marina.
Once a month, set aside 30 minutes for a systematic walk-around inspection. Most items take less than two minutes to check. Catching a small problem in this pass saves significant time and money downstream.
Every three months — aligned with the seasons — run through this deeper inspection pass. Spring (before the heat), summer (heat management), fall (before winter moisture), and winter (cold and damp) each have distinct priorities.
A stationary rig accumulates ground moisture against its underbelly in ways a traveling rig doesn’t. Inspect annually for water damage or pest intrusion. Rodent entry through underbelly gaps is a significant issue in outdoor parking environments — steel wool and appropriate caulking at any gap larger than a pencil diameter is standard preventive practice. Good Sam’s RV service network can assist with underbelly inspections and repairs if you need professional support.
Southern California’s UV index is among the highest in the continental US — the EPA UV Index data regularly records levels of 9–11+ across the Inland Empire from March through October. In addition to tire covers, consider UV-protective window film or exterior covers for windows receiving sustained direct sun. A quality RV wax with UV inhibitors applied annually makes a visible difference in finish longevity.
The open space network surrounding the hills east of downtown San Jacinto offers miles of ridge walking and canyon hiking with mountain views that rival anything in the region. Spring — before summer heat sets in — is the optimal season. Early morning hikes between 6 and 9 AM offer cool temperatures and abundant wildlife activity. For trail discovery and GPS maps of the broader network, AllTrails has user-reviewed routes throughout the San Jacinto Mountains area.
Hemet and the San Jacinto Valley have solid RV service infrastructure. For parts and supplies, Camping World has locations within the region carrying most standard maintenance materials including lap sealant, slide seal treatment products, and tire covers. For professional service, several independent RV service shops operate in the Hemet area.
