2016 Keystone Montana: Expired Tires, Zero Lights

We inspected a 2016 Keystone Montana fifth wheel recently, and this one wasn't sitting on a sales lot waiting for a buyer. It was parked at the owner's home under a permanent awning, decking installed underneath, skirting wrapped around the base, tucked under a shelter that had clearly been its home for a while. The owner had lived in it since buying it about ten years ago, and it had been moved to this spot and settled in ever since. The reason for our visit was practical: a transport company was scheduled to hitch this Montana up and haul it two hours away to Oklahoma, and somebody needed to confirm it could actually make that trip safely.

What we found means that trip needs to wait.

Four Tires, One Common Problem

Every single tire on this Montana, streetside and curbside, both axles, carries a DOT date code showing it's more than six years old. Not one or two. All four. Rubber compounds break down over time whether or not the tire has any tread left, and a trailer that's spent a decade parked in one spot, out of regular use, often ages out long before the tread ever wears down. We flagged all four as Life Safety findings and recommended a qualified RV technician evaluate them before this trailer gets towed anywhere, let alone two hours down the highway. A blowout on a fifth wheel at speed isn't a minor inconvenience. It's the kind of thing that ends a trip before it starts, or worse.

The Roof Told Us It Needed a Closer Look

We also noted the roof was coated in a layer of dirt heavy enough that we couldn't thoroughly check for tears, punctures, or failing sealant underneath it. That's not a pass or fail finding on its own, it's a flag. Dirt hides deterioration, and a roof membrane with hidden compromise is how small leaks turn into soft subfloors and water-damaged walls down the line. We'd want this Montana's roof cleaned and re-inspected before anyone signs off on its condition, especially with a long tow ahead of it.

When the Lights Just Don't Come On

Here's where things got more serious. During our 7-pin connector test, none of the marker lights activated. None. The rear turn signals were dim and inconsistent when they did fire, and we couldn't get the brake lights to activate at all. That's three separate Life Safety findings tied to the trailer's exterior lighting, and together they mean this Montana isn't legally or safely towable on public roads in its current state. A driver behind this trailer at dusk on the highway to Oklahoma would have no warning it's slowing down, turning, or even there.

Slideouts, Leveling, and Dead Batteries

Living in a fifth wheel parked under a shelter for years has a way of quietly sidelining systems nobody thinks to run. The slideouts and the leveling system hadn't been operated or tested in years, and we had no way to confirm either would function correctly when called on for the move or for a new owner down the road. On top of that, the batteries were dead on arrival, which meant we couldn't power up and test everything we'd normally check with the coach running on its own systems. All of that adds up to more unknowns riding along on a trip that was supposed to be a straightforward transport.

Why This Kind of Thing Gets Missed

A transport company hooking up a trailer for a scheduled move has no reason to check DOT codes stamped into a tire's sidewall, and there's no way to catch a lighting failure without wiring up a 7-pin tester and watching every circuit fire, or not, one at a time. Dead batteries and slideouts that haven't moved in years don't announce themselves either, not until someone's stuck trying to use them. This is exactly the gap a documented, standards-based inspection is built to close. We follow the NRVIA's Code of Ethics and Standards of Practice on every job, which means the findings above aren't opinions, they're documented conditions tied to a repeatable process.

A trailer like this Montana can still make that trip to Oklahoma, and it can still be a solid rig once it's there. It just needs the tires, lights, and a few other things sorted out first, not discovered halfway down the highway.
