Dometic CoolAir RTX-SPXT-IK Universal Installation Kit

The Dometic CoolAir RTX-SPXT-IK is the universal installation kit that gets a CoolAir parking cooler mounted right the first time. If you're putting an RTX 1000, RTX 2000, or SPX-T climate unit on a panel van, light truck, or work vehicle, this is the bracket set that ties the unit down using the fastening points already built into the vehicle. No guesswork, no fabricating your own mounts from scratch.

Here's what it actually does. The kit uses a two-bracket fastening system rated to hold up to 300 pounds, so the CoolAir unit stays put whether you're parked overnight at a truck stop or working down a rough access road to a job site. Because it references existing fastening points, you're not drilling a field of fresh holes into a roof you'd rather keep sealed and dry. That matters. Every hole you don't cut is one less spot to chase a leak down the road.

Who's this for? Long-haul drivers who sleep in the cab and want real cooling without idling the engine all night. Van builders adding a low-draw air conditioner that runs off the house batteries instead of shore power. Fleet managers and service outfits who need the same climate unit installed the same way across a whole run of vehicles. If you've got an RTX or SPX-T unit and a vehicle to put it on, this kit is the bridge between the two.

The appeal of a CoolAir parking cooler is simple. You get to run air conditioning while the engine's off, which means quieter nights, no fuel burned at idle, and no wear piling up on a motor that's doing nothing but spinning the compressor. In a lot of places idling laws make overnight engine-on cooling a non-starter anyway. A rooftop unit solves that, and this kit is what holds it up there safely.

Fitment is the whole point of a universal kit like this one. It's designed for all common types of panel vans, light trucks, and special vehicles, and it's built specifically around the RTX and SPX-T CoolAir family. The RTX 1000 and RTX 2000 are Dometic's rooftop parking coolers built to cool a cab or sleeper without the engine running, and the SPX-T rounds out the lineup. This kit speaks their mounting language, so the unit lands where it should and bolts down clean.

One thing we'll say plainly, because nobody likes a surprise on the loading dock: this is the installation kit, not the air conditioner. You supply the CoolAir RTX or SPX-T head unit, and this kit handles getting it mounted. If you're ordering a full setup, make sure the climate unit itself is on the order too. Ordering the kit alone and expecting a cooler in the box is the one mistake we see people make.

Install is within reach for anyone comfortable with hand tools and a little roof work. The two-bracket design keeps the parts count sensible, and leaning on the vehicle's existing fastening points means you're working with the structure that's already there rather than engineering a mount from zero. Take your time on the seal, check your load rating against your unit, and torque everything down properly. Done right, it's a mount you set once and forget.

This is a genuine Dometic part, number 9100300152, so it fits the CoolAir units the way the factory intended and carries the full Dometic warranty. When you're bolting a heavy climate unit to the top of a vehicle that's going to see highway speed and vibration for years, the right bracket kit isn't the place to cut a corner. Get the unit mounted on hardware that was engineered for it.
