Is There A Class C Diesel RV With A Garage?

Toy haulers are often very large RVs that have a portion dedicated to a garage/storage space. As such, it’s rare to find a Class C diesel RV with a garage. These vehicles effectively have to double as a toy hauler, but there is one model that balances everything beautifully.

Luckily, Renegade RV has a few different floor plans that fit the bill. Their builds come with a variety of chassis options, many of which are powered by diesel engines. The IWS Signature Series Motocross Edition 45′ Quad Slide is a real mouthful, but it’s also one of the best options for a Class C diesel RV with a garage.

This is a floor plan that manages to fit all the comforts of home (and a spacious garage) within a motorhome floor plan. We’ll explore some of the features of this Class C diesel RV below. Turns out, it has a lot more to offer than just a garage!

The specifications for Renegade motorhomes may vary a bit depending on the floor plan you choose. But if you stick with an IWS Signature Series Motocross Edition 45′ Quad Slide, you can expect the following information to be true:

  • Total Vehicle Length: 45 feet
  • Fuel Capacity: 120 gallons
  • Fresh Water Capacity: 150 gallons
  • Garage Dimensions: 114″ long x 100″ wide x 90″ tall


Now that the technical stuff is out of the way, let’s talk about all the great features of this Class C diesel RV with a garage. Since this vehicle is 45 feet long, there’s plenty of room for amenities.

Let’s start at the back! The very rear of this motorhome is where you can find the garage. This space spans the entire width of the RV and is about 9 feet long. It’s mostly just open space that can be used to store bulky gear or even small vehicles. A stacked washer and dryer sit in one corner of this room, so it can double as a laundry room if necessary.

The main bedroom sits on the other end of this garage. This section has a pair of opposing slideouts that expand the space. The room also has a mini king bed, tiled floor, a wall-mounted TV, and a spacious closet. The bathroom separates the master bedroom from the rest of the RV.

This bathroom spans the width of the RV and has sliding doors on both sides to make it easily accessible. It’s fairly roomy for a motorhome bathroom and has all the essentials you need to refresh and relax. On the other side of the bathroom, we have the combined living room and kitchen.

This section also has a pair of opposing slideouts. One contains a dinette and Flexsteel sofa that can convert into another bed. The other holds the huge residential refrigerator, sink, microwave, and cooktop. Overhead cabinets line the walls in this space, and there’s also a nice pull-out pantry.

To round out the equation, there’s an extra bunk above the driver’s cab. Combined with all the other sleeping spaces in this RV, this motorhome is well equipped to host families and large groups.

Special features

Most RVs have the same standard equipment, but the quality and build of each item may vary. This Class C Diesel RV with a garage goes above and beyond in many respects! It has some special features that really set it apart from the competition.

Some of the best features of the IWS Signature Series Motocross Edition 45′ Quad Slide include:

  • Maple hardwood cabinets
  • Stonecast deep bowl kitchen sink
  • 18 cubic ft. stainless steel residential refrigerator (with ice maker)
  • Deluxe bath faucet
  • Whole house water filtration
  • Solar panel prep
  • Multiple 32″ Smart LED TVs
  • Keyless entry
  • 18′ awning
  • And much more!

Upgrades and add-ons

In addition to the standard features, buyers can also select from a huge list of upgrades and add-ons. Almost every part of this motorhome can be customized, so you can create the perfect RV of your dreams. There are honestly too many upgrades to mention here, so I’ll just cover some highlights from each of the major areas of this motorhome.

  • Exterior: 3/4 Pass-Thru storage compartment, stainless side swing baggage doors, and grey spray bed liner in all cargo boxes.
  • Interior: Ceiling fan installations, free-standing dinette substitute, quartz countertops, electric heated tile, central vacuum system, and a stainless steel dishwasher.
  • Garage: A choice of two insulation packages, tinted side windows, optional bunk bed installations, and an access hatch in the roof.
  • Water System: 10-gallon water heater, vessel bowl sink in the bathroom, tiled shower, Flo-jet macerator, and a double bowl kitchen sink.
  • Mechanical: 35,000 BTU LP gas furnace, additional outlets, Max-Aire roof vent, LP coupler in the storage compartment, and an additional 8-D AGM battery.
  • Electrical: Upgraded Smart TVs, motorized TV slide, exterior entertainment center, handheld CB radio, and stationary satellites.

Buyers can also choose from a variety of decoration options for the interior and exterior. There are lots of different design schemes and paint jobs that are available for this design. With all these choices, you can keep it as simple or complex as you want!

Additional floor plans

Due to the amenities and overall size, we believe that the IWS Signature Series Motocross Edition 45′ Quad Slide is the best Class C diesel RV with a garage. However, there are a few other floor plans by the same manufacturer that give it some real competition.

In terms of the overall layout, these motorhomes are almost identical. They just have a few changes in terms of the measurements and some of the upgrades. For instance, many of the other floor plans don’t have a washer and dryer in the garage. One also has three slideouts instead of four.

These changes are pretty small, but they could make a difference. Feel free to explore the IWS Renegade product page here to compare and explore all the floorplans for this Class C diesel RV with a garage.

  1. That is the best walk though I have seen by IWS . I have owned three Wanderlodges and two 45′ newells and your presentation impressed me. The only comment I can make is the lack of a navigation system.
    I understand that if you have a smart phone it will display the program on the screen, but those programs although are good, I have developed a better one made from on hand experience of motohoming since 1982. I have a map of low bridges, campgrounds that will hold a 40 and 45 foot motorhome, road notes, mountain passes, fuel stops with links to their websites, walmart’s that allow parking overnight and those that don’t and much more.
