The delivery day walk-through can feel like the finish line. You have the keys in sight, travel plans on the calendar, and a dealer representative moving quickly through a long list of features. That is exactly when small problems get missed. These RV PDI inspection examples show what a real pre-delivery inspection can uncover before a minor defect becomes a ruined first trip, a service appointment weeks away, or an expensive repair bill.
A PDI, or pre-delivery inspection, is more than turning on a few lights and checking that the floor is clean. It is a hands-on test of the RV’s systems, components, safety equipment, and paperwork before ownership changes hands. The goal is simple: find problems while the responsibility to correct them is still clear.
What a Proper RV PDI Should Look Like
A useful PDI is slow enough to test systems under normal operating conditions. The RV should be connected to shore power, have water available, and be set up so slides, leveling equipment, appliances, and electronics can all be operated. A quick walk-around may spot obvious cosmetic damage, but it will not tell you whether a GFCI outlet trips correctly, a water pump cycles unexpectedly, or an air conditioner can carry a load.
Some dealers perform their own PDI before a buyer arrives. That is expected, but it is not the same as having an inspection performed with your interests in mind. Whether you inspect it yourself, bring along an experienced RVer, or hire an independent inspector, plan to take your time. For a large motorhome or a feature-heavy fifth wheel, several hours is not excessive.
The best inspection notes are specific. “Bathroom leak” is hard to act on. “Water drips from the hot-side PEX fitting below the bathroom sink after the pump runs for two minutes” gives the service department a clear repair target.
RV PDI Inspection Examples for Every Major System
Water systems: test for leaks you cannot see at first glance
Water damage is one of the costliest RV problems because it can spread behind walls, below flooring, and inside cabinets long before it becomes obvious. Start by connecting city water and opening every faucet, including the outdoor shower, kitchen sprayer, toilet, and low-point drains. Look inside cabinets and access panels while water is flowing.
One common PDI finding is a loose fitting under a sink that only drips when the faucet runs at full pressure. Another is a water pump that keeps cycling when all faucets are off, which can point to a leak, a loose connection, or a valve that is not sealing. Fill and drain the sinks and shower to make sure the drains flow properly and no water appears underneath the RV.
Check the fresh tank fill, water heater, tank monitor panel, and sewer connections as well. A monitor reading may be inaccurate, but it should be documented before delivery rather than shrugged off as “just an RV thing.”
Electrical systems: verify both shore power and battery power
Electrical problems can hide behind a glowing control panel. Test the RV on shore power, then test 12-volt functions on battery power. Run interior and exterior lights, exhaust fans, USB ports, televisions, powered awnings, and all outlets. Use the test and reset buttons on GFCI outlets, especially in the kitchen, bathroom, and exterior compartments.
A practical example: the microwave works, but several receptacles do not. The issue may be a tripped GFCI, a loose connection, or a mislabeled breaker. It is easier to diagnose before delivery, when the RV is already plugged in and the seller is responsible for correcting the fault.
If the RV has an inverter, confirm which outlets it powers and whether it transfers correctly between battery and shore power. Check that the converter is charging the batteries. If you are buying a solar-equipped RV, confirm that the controller shows charging activity in daylight and that the battery disconnect switch does what it is supposed to do.
Slides, leveling, and awnings: listen and watch every movement
A slide room should extend and retract smoothly, seal evenly, and avoid rubbing trim, flooring, or cabinetry. Run every slide more than once. Watch the exterior seals and check the interior corners afterward. A slide that sounds strained, jerks during travel, or leaves a visible gap deserves attention before you accept the unit.
Leveling systems need the same treatment. Extend the jacks on a stable surface, verify that the controls respond, and retract them fully. Look for hydraulic fluid leaks and confirm that warning alarms and indicator lights function. On travel trailers and fifth wheels, check the front landing gear, stabilizers, breakaway switch, coupler, safety chains, and electrical connector.
Open the awning completely. Let it run long enough to show whether the fabric tracks correctly and whether the arms bind. Look for fabric tears, loose mounting hardware, missing fasteners, and water pooling in the awning when it is lightly sprayed.
Appliances and climate control: let them run long enough to fail
An appliance that powers on is not necessarily working correctly. Give each system time to perform. Run the air conditioner for at least 20 minutes, listen for unusual vibration, and make sure cool air reaches the vents. Test the furnace and confirm that it ignites, blows warm air, and shuts down properly.
Check the refrigerator on the available power sources for that model. Test the water heater, cooktop, oven if equipped, microwave, range hood, and vent fans. If the RV has a washer, dryer, dishwasher, or fireplace, operate those too. Make sure every appliance door latches securely for travel.
A frequent PDI example is an air conditioner that blows air but never gets cold because of a wiring, thermostat, or installation issue. Another is a furnace that starts its fan but fails to ignite. Those are not items to “see how they do on your first trip.” Ask for a repair and a retest while you are still at delivery.
Generator and chassis: test under load, not just at idle
For a motorhome with an onboard generator, start it from the interior control and at the generator itself if possible. Let it warm up, then place it under a meaningful load by running the air conditioner and other approved appliances. Confirm that power transfers correctly, check for fault lights or codes, and look for fuel, oil, or coolant leaks. A generator that starts but shuts down under load is not ready for dependable travel.
On a motorhome, inspect tire condition and date codes, lights, mirrors, wipers, steps, dash controls, backup and side cameras, and the operation of the parking brake. Take a road test if the seller allows it. Pay attention to pulling, braking, steering vibration, warning lights, and rattles from the coach.
For towable RVs, inspect the tires, brakes, suspension components, frame welds, and underbelly. Confirm the VIN on the paperwork matches the RV. New does not always mean problem-free. Units can sit for long periods, be moved around a lot, or pick up damage during transport.
Do Not Skip Fit, Finish, and Safety Details
Cosmetic items may seem less urgent than a leaking pipe, but they still belong on the punch list. Open every cabinet, drawer, exterior storage door, window, blind, and screen. Check flooring transitions, wall panels, trim, caulking, furniture, and bed platforms. Look at roof seams and sealant from a safe position. If roof access is safe and permitted, inspect around vents, skylights, antennas, and air conditioners for gaps or damaged sealant.
Test smoke alarms, carbon monoxide alarms, propane detectors, fire extinguishers, emergency exits, and the LP shutoff. Confirm that required manuals, keys, remotes, cords, hoses, adapters, and accessories are included. Missing items are much easier to resolve before the paperwork is complete.
Turn RV PDI Findings Into a Clear Punch List
When you find an issue, take a photo or short video and write down the location, the condition that caused it, and the date. Ask the seller to put repairs in writing, including whether the work will be completed before delivery or scheduled afterward. If a repair is made, retest it. A cabinet latch adjusted in front of you is one thing. A water leak or electrical fault should be tested again under the same conditions that exposed it.
Avoid accepting vague explanations such as “that is normal” without a demonstration or documentation. RVs do have quirks, and not every minor adjustment should stop a purchase. But safety defects, active leaks, failed appliances, damaged seals, nonworking systems, and incomplete promised equipment should be addressed clearly. Your purchase agreement may affect what happens if repairs are delayed, so review it before signing final documents.
A thorough PDI is not about being difficult with a dealer. It is about starting RV ownership with fewer surprises and a complete record of the RV’s condition. If you are taking delivery in the Palmetto or Tampa Bay area and want practical help checking an RV before it becomes your problem, True Test RV brings the same owner-focused mindset to inspections that it brings to repairs. Take the extra time at delivery – it is one of the easiest ways to protect the trips you have been looking forward to.
