Your Guide to Isuzu Commercial Trucks

When it comes to the success of your business, few things are as important as having the right tools and equipment for the job. For many, no tool is more important than a powerful truck built to help you get some serious work done.

As you look at box trucks for sale near Folsom, you should consider what Isuzu offers. They have some of the most powerful chassis cabs on the market, making for remarkable box trucks in a wide range of sizes. Getting the right one comes down to knowing what you need, but even with that in mind, it can be tricky to navigate everything Isuzu offers.

So let’s take a look at the main models available and what differentiates them, so you have a better sense of which one will work best for your business.

The Isuzu N-Series Gas Trucks

One of the easiest ways to determine which truck is right for you is to figure out how much weight your box truck needs to handle, and then go from there. Isuzu offers three series of commercial trucks with conventional engines, giving you plenty of impressive options to choose from.

Starting, we have the N-Series of trucks with gas engines, powered by an impressive 6.6L V8 that delivers 350 hp and 425 lb-ft of torque. Some come with an eight-speed transmission, while others have a six-speed.

There are four options here, each with different classes and weight ratings to consider. So let’s look at each one along with its Gross Vehicle Weight Rating (GVWR), Gross Combined Weight Rating (GCWR), and available body lengths:

NPR Class 3 Truck

  • GVWR: 12,000 lbs
  • GCWR: 18,000 lbs
  • Body Lengths: 10 to 24 ft.

NPR-HD Class 4 Truck

  • GVWR: 14,500 lbs
  • GCWR: 20,500 lbs
  • Body Lengths: 10 to 20 ft.

NQR Class 5 Truck

  • GVWR: 17,950 lbs
  • GCWR: 23,950 lbs
  • Body Lengths: 12 to 22 ft.

NRR Class 5 Truck

  • GVWR: 19,500 lbs
  • GCWR: 25,500 lbs
  • Body Lengths: 12 to 24 ft.

As you can see, there are some significant differences here, especially when you look at the weight ratings for each of these. Note that all four of these models are available with either a three-passenger standard cab or a seven-passenger crew cab. Standard cabs allow for the longest body lengths, so keep that in mind when considering these options and choosing the right one for your business.

The Isuzu N-Series Diesel Trucks

If you prefer a diesel engine over a gas powertrain, Isuzu has you covered with four terrific options that are similar to what’s available with their gas engines. These models are powered by a 5.2L diesel engine that delivers 215 hp and 452 lb-ft of torque; each comes paired with a six-speed automatic transmission with double overdrive. Just like the gas models, you have four N-Series diesel trucks to choose from, so let’s see what they offer:

NPR-HD Class 4 Truck

  • GVWR: 14,500 lbs
  • GCWR: 20,500 lbs
  • Body Lengths: 10 to 20 ft.

NPR-XD Class 4 Truck

  • GVWR: 16,000 lbs
  • GCWR: 22, 00 lbs
  • Body Lengths: 10 to 20 ft.

NRR Derate Class 5 Truck

  • GVWR: 17,950 lbs
  • GCWR: 23,950 lbs
  • Body Lengths: 10 to 22 ft.

NRR Class 5 Truck

  • GVWR: 19,500 lbs
  • GCWR: 25,500 lbs
  • Body Lengths: 10 to 24 ft.

You can see one of the biggest differences here is that there’s no Class 3 truck in the N-Series diesel lineup, unlike the selection of gas trucks. This means that these diesel box trucks start at higher weight ratings, but if a Class 3 truck is the right pick for you, then you’ll likely want to go with a gas model.

Much like the gas trucks, the N-Series diesel trucks are all available with either the standard cab or crew cab, so you can get the right configuration for what your business needs. This can be especially important for moving companies or when you need more than two or three people in your trucks to make deliveries around Folsom.

The Isuzu F-Series Diesel Trucks

Finally, we have the F-Series of trucks; there is only one version of this lineup available, so you don’t have to consider two different powertrains. These are heavier-duty trucks with higher weight ratings; if you need something that can handle massive weight, these might be the best place to start.

Every F-Series truck is powered by an incredible Cummins diesel engine that delivers 260 hp and 660 lb-ft of torque at just 1600 RPM, ensuring your box truck has plenty of muscle to get where it needs to go each day. These models all come with an Allison six-speed automatic transmission, so your team can enjoy smoother driving.

You’ve got three options available with the Isuzu F-Series:

FTR Class 6 Truck

  • GVWR: 25,950 lbs
  • GCWR: 30,000 lbs
  • Body Lengths: 14 to 30 ft.

FVR Derate Class 6 Truck

  • GVWR: 25,950 lbs
  • GCWR: 33,000 lbs
  • Body Lengths: 14 to 30 ft.

FVR Class 7 Truck

  • GVWR: 33,000 lbs
  • GCWR: 33,000 lbs
  • Body Lengths: 14 to 30 ft.

One thing you’ll notice about these three models is that they’re Class 6 and Class 7 trucks, whereas the N-Series included Class 3 to Class 5 trucks. So across these three series, Isuzu meets a wide range of needs, giving you the freedom to get exactly what your company needs from your next box truck.

You can see that the weight ratings here are significantly higher than the N-Series trucks can handle, and they can accommodate much longer boxes, giving you greater freedom and flexibility to get what you need.

Which Isuzu Box Truck Is Right for You?

The answer depends entirely on your business needs, though the differences between these series can guide some of your decision-making. Start with how much weight your truck needs to handle, as this makes it easier to choose the right weight rating for your next truck.

From there, you can consider the cab size and box length you’re looking for, as all three series offer a wide range of options, giving you the freedom to get something that perfectly meets your needs.

We should note that the F-Series is only available with the three-passenger standard cab and not the larger crew cab. This allows it to have longer overall lengths and wheelbases, which is part of why it can fit longer boxes.

But if you need something for a team of more than three people, then you’ll want to stick to the N-Series. Of course, if you need the capabilities of the F-Series and to get more people to a jobsite, then you can always have them take a Ford work truck and meet up with the team in your box truck.
