Designed & Assembled In the USA · 2-year unlimited-hour warranty · Parts at any automotive parts store
One unit. No trim-level games.
What you’re buying: the Star Edition
26,000 BTU of heat and air conditioning, some of the highest output in the industry. It runs on a reliable 3-cylinder Kubota diesel, the one component that isn’t made in the USA.
It keeps the bunk cool in July and warm in January, keeps your batteries charged, and runs your hotel loads all night on roughly a quarter of the fuel your main engine burns at idle.

What it costs, actually
$14,999 MSRP, and that includes installation. Most of the market lands somewhere between $12,000 and $17,000+ once install is on the invoice. So whatever quote you’re comparing, ask whether installation is included. That’s where the surprises live. The full math is in our cost breakdown.

- Diesel you stop burning each year
- ~$9,000/yr
- Fuel money that stays in your pocket
- 14mo
- Typical break-even. Then it’s all yours

A warranty without an asterisk
Two years. Unlimited hours.
A lot of APU warranties cap you at a set number of hours. Read the fine print on anything you’re comparing, because an OTR truck blows through those caps fast. Ours doesn’t have one.
Support that outlives the warranty
24/7 USA-based tech support for the life of the unit. A real person on the phone, any hour, with diagnostics while you’re on the road.
Parts at any automotive parts store
When it needs a belt or a filter at the 1,000-hour PM, it’s off the shelf. No proprietary lock-in, no waiting on somebody’s dealer network while your truck sits.
Two ways to get one
Buy direct, or through a dealer
Direct from the shop in Lemont, IL
We install it in one day at our facility, and you can watch it go on. The phone gets answered by the people who build the unit, not a call center.
Through 100+ dealers & service centers
Sold, installed, and warranty-serviced through authorized locations across the US and Canada. Install time varies by shop.
Financing is available through Time Payment, so it can start paying for itself before it’s paid off.
Thinking about a used APU? Used units look cheap up front. What the listing doesn’t show is hours on the engine, how it was maintained, and whether any warranty survives the sale. Call us before you buy either and we’ll tell you what to check, no pressure. A used unit that was maintained right can be a fine deal. Most weren’t.
