I’ve walked through hundreds of trailers. Factory floors in the US. Shipping containers at ports. Our own showroom. Competitor showrooms (yes, I visit those too). Customer rigs returning from 5,000 km trips. Every time I walk through a trailer, I check the same things in the same order. Here’s the list.
The Outside (Before You Open the Door)
1. The hitch and coupler. I start here because this is the part that connects the trailer to the vehicle, and if it fails, nothing else matters. I check the ball coupling for wear (any sloppiness means it’s been used without proper tightening), the safety chain attachment points for cracks or deformation, the breakaway cable for fraying, and the tongue jack for smooth operation. A well-maintained hitch moves freely, locks positively, and shows no rust at the connection points. A neglected hitch tells you how the rest of the trailer has been treated.
2. The frame and underside. I get on my knees and look under the trailer. I’m looking at the frame coating (powder-coated or painted steel, no exposed bare metal, no active rust), the axle welds (smooth, consistent, no cracks), the holding tank mounts (secure, no sagging), and the underbelly material (sealed, no tears or hanging sections). On a US-built trailer, the frame is typically a Norco or equivalent engineered chassis with a protective coating. On a conversion, the frame is whatever the original vehicle had, which may or may not be adequate for the added weight of a living space.
3. The seals. I run my finger along every exterior seal: the roof-to-wall joint, every window frame, the door frame, and the seals around any roof-mounted equipment (AC unit, vent fans, antenna). Sealant should be continuous, flexible, and firmly adhered. Any cracking, lifting, or gaps mean water has a path inside, and water inside a trailer wall causes more damage than any other single problem. This check takes five minutes and tells me more about a trailer’s condition than any spec sheet. Details on seal maintenance: Serviceability Index.
4. The sidewalls. I press the exterior wall panels in several spots. The wall should feel solid and uniform. Any soft spots, depressions, or areas where the outer skin separates from the inner structure indicate delamination, which is caused by water intrusion and is expensive to repair. On a US-built laminated wall, delamination is rare if seals are maintained. On a conversion with plywood walls and a vinyl or metal skin, it’s common after a few monsoon seasons.
5. The tyres. I check tread depth, sidewall condition (cracks, bulges, weathering), and manufacture date (the DOT code). A tyre that’s more than five years old is a liability regardless of tread. I also check the spare and its pressure.
The Systems (Open the Panels)
6. The electrical panel. I open the breaker box. On a US-built trailer, every circuit is labelled: AC, water heater, lights, outlets, fridge. The wiring is routed neatly, secured with clips, and uses colour-coded wires of appropriate gauge. On a conversion, I often find unlabelled breakers, loose wiring, incorrect gauge, and connections made with electrical tape instead of proper terminals. The panel tells you whether an electrician or an engineer built the system.
7. The gas compartment. I open the exterior gas cylinder door. The compartment should be sealed from the living space (gas-tight partition), vented to the exterior (so leaks dissipate outside), and have a proper regulator mounted to the partition wall. The gas line from regulator to kitchen should be rigid copper or approved flexible hose with no joins inside the wall cavity. I check for the flame failure device on every burner by lighting it, blowing it out, and confirming the gas cuts within 30 seconds. This is the check I never skip. The full LPG system: Caravan Cooking in India.
8. The plumbing. I turn on the water pump and run every faucet. I look under the kitchen sink and under the bathroom sink for drips at the connections. I flush the toilet and listen for the refill cycle. I check the water heater connections (usually behind a panel). PEX or copper plumbing with push-fit or crimped connections is what you want. Rubber hose with hose clamps is what you find in conversions. The difference in leak rate over five years is substantial.
9. The LP and CO detectors. I press the test button on every detector. They should alarm immediately. A dead detector or a missing detector is a disqualifier. These are not optional accessories. They are safety devices that prevent the worst-case scenario in a confined gas-equipped space.
The Living Space (The Stuff You Actually Touch)
10. The cabinet hardware. I open and close every cabinet, every drawer, every overhead compartment. The latches should hold positively (the kind that click and require deliberate force to release, not the kind that pop open when the trailer sways). The hinges should be metal, not plastic. The drawer slides should be full-extension ball-bearing, not friction slides. This sounds trivial. It’s not. You open and close these cabinets thousands of times. Cheap hardware fails within a year. Good hardware lasts the life of the trailer.
11. The fridge. I check the fridge type: compressor (good) or thermoelectric (inadequate for Indian conditions). I open the door and check the seal (magnetic strip, firm closure). I verify it’s running on 12V battery when unplugged from shore power. A compressor fridge that maintains temperature on battery for 24+ hours is a properly specified unit. One that warms up within a few hours is undersized or poorly insulated.
12. The bathroom. I step inside. I close the door. I turn on the shower. I flush the toilet. I check water pressure, hot water response time, and drainage. I look at the floor for soft spots (indicating water damage beneath). The bathroom is where build quality is most visible and where conversions cut the most corners. A bathroom that works properly in a 16-foot trailer is a feat of engineering. A bathroom that doesn’t is the fastest way to ruin a trip. Build quality comparison: US-Built vs. Indian Conversions.
13. The bed. I sit on it. I lie on it. I check the mattress thickness and density (at least 6 inches of medium-firm foam for a proper night’s sleep). I check whether the bed lifts for storage access underneath (it should). I check the headroom. A bed that looks good in a photo but gives you back pain by night three is not a bed. It’s a shelf.
14. The stove and range hood. I light every burner. I check flame quality (blue, steady, not yellow or flickering). I turn on the range hood fan and hold a piece of tissue near the vent to confirm airflow direction (it should pull air up and out, not recirculate). I check whether the hood vents to the exterior or just filters and recirculates. Exterior venting is the standard on US-built trailers. Recirculating is what you get in conversions, and it doesn’t work for Indian cooking.
15. The overall smell. This sounds strange, but it’s one of the most telling checks. A well-built, well-maintained trailer smells like nothing, or faintly like upholstery and wood. A trailer with water damage smells musty. A trailer with a gas issue smells faintly of LPG. A trailer with poor ventilation smells stale. A conversion that used formaldehyde-heavy adhesives smells chemical. Your nose knows things your eyes miss.
Why This List Matters
I didn’t write this list to impress you with how much I know about trailers. I wrote it because most buyers in India have never been inside a caravan before they walk into a showroom, and they don’t know what to look for. They look at the bed. They look at the bathroom. They check whether the lights turn on. And then they make a purchase decision based on aesthetics and price.
The fifteen items above are the things that determine whether your trailer is still working properly in year three and year five. The hitch, the frame, the seals, the electrical panel, the gas compartment, the plumbing, the detectors, the hardware, the fridge, the bathroom, the bed, the range hood, the walls. These are the things that separate a trailer you love from a trailer you regret.
When you visit our showroom, I’ll walk you through this list on the actual trailer you’re considering. Every panel, every compartment, every system. Because the engineering is the product, and I want you to see it before you buy it.
If you’re evaluating any caravan, ours or someone else’s, use this list. If the seller won’t let you open the electrical panel or look under the trailer or test the gas system, that tells you everything you need to know.
