What we support
APU power for the way your trucks actually work.
From diesel systems to battery-electric packages, we can review equipment and installation combinations tied to commercial truck operations.
Electric + Battery APUs
Battery-based and electric systems designed to reduce engine idling and fuel use.
Complete Install Packages
Eligible equipment, installation and related components packaged into one commercial purchase.
Qualifying Used APUs
Used systems from eligible commercial sellers may be considered.
Dealer Programs
Put a monthly payment path directly into the APU sales conversation.
Installer Programs
Help customers move from quote to installed system without a separate cash hurdle.
The cost you already have
Idle has a monthly payment too.
Every hour the main engine runs just to heat, cool or power the cab is an operating expense. An APU can redirect part of that recurring fuel spend toward equipment that keeps working after the payment is gone.

If estimated monthly fuel savings approach or exceed the payment, the purchase can start looking less like a cost conversion and more like an operating decision.
How it works
From APU quote to powered cab.
1. Start with the equipment
Share the APU, seller or installer, total package and purchase price.
2. Review the business
We look at the transaction together with the operating story behind the truck or fleet.
3. Choose a monthly path
Review available structures that fit the equipment and business profile.
4. Keep the install moving
Documents and vendor coordination help move the purchase toward funding.
For APU dealers + installers
Sell the savings. Give them a monthly path.
An APU already has an operating-cost story. Add a payment path at the point of purchase so customers can compare the monthly cost of the system against the cost of continuing to idle.

EARLY STAGE. REAL OPERATION.
A newer trucking business can still have a real equipment need.
Revenue, deposits, operating history, customers, owner experience and the role the APU plays in the business can all matter to the story.
For dealers and installers: don’t automatically lose a buyer just because the company is young. Bring us the full picture.
