999-Gallon Capacity Slide-in Unit

Compact Power for Routes That Demand Flexibility

When your route demands more and a standard slide-in just doesn’t cut it, the 999-gallon pump truck tank is the answer. KeeVac’s 999-gallon slide-in is the largest capacity unit in our slide-in lineup, purpose-built for operators who need serious pumping volume without committing to a full-size dedicated truck body.

Whether you’re running a septic route, servicing grease traps, or handling portable sanitation work across a wide service area, a 999-gallon pumper truck setup gives you the hauling power to extend your runs, reduce disposal trips, and keep your crew productive in the field.

Why Operators Choose the 999 Gallon Slide-In

This isn’t a unit for light-duty work. The 999-gallon truck tank is built for operators who are serious about efficiency and long-term durability. Here’s what makes it stand out:

  • Maximum slide-in capacity: The largest tank we offer in a slide-in format, ideal for high-demand routes
  • Drop-in versatility: Mounts in a compatible full-size pickup bed, so you’re not locked into a dedicated truck chassis
  • Built KeeVac tough: Same aluminum tank construction and quality standards we apply across all our builds
  • Reduced disposal runs: More gallons on board means fewer trips to the dump station
  • Route flexibility: Scale up without scaling to a full truck body investment

If you’ve been running a smaller slide-in and outgrowing it, this is the logical next step before moving to a full-size septic or grease truck.

Frequently Asked Questions

Quick answers to help you choose the right unit and configuration.

What is a 999-gallon pump truck tank slide-in?

It’s a high-capacity vacuum tank unit designed to mount in a compatible full-size pickup truck bed. It gives operators serious pumping volume without requiring a dedicated full-size truck body, making it one of the most versatile options in the KeeVac lineup.

How is the 999-gallon slide-in different from a full-size septic or grease truck?

A slide-in mounts to your existing truck, which lowers upfront investment and keeps your rig flexible. A full-size build offers more customization, greater chassis options, and is better suited for dedicated route fleets. If you’re growing and need the full package, check out our Septic Tank Trucks and Grease Vacuum Trucks.

Is the 999-gallon truck tank compatible with my pickup?

Compatibility depends on your truck’s bed size, payload rating, and chassis strength. Our team will walk you through specs before you commit. Give us a call at (303) 789-9440 or submit a quote request.

Does KeeVac support slide-in units after the sale?

Yes. Our Parts Department, Parts Request system, and maintenance support are available to all KeeVac customers, including slide-in owners.
