Exterior Dimensions and Weights: The Foundation of Your Journey

Alright, let's start with the basics: the exterior dimensions and weights of the 2017 Grand Design Momentum. These figures are crucial for everything from ensuring your tow vehicle is up to the task to navigating campgrounds and parking your rig. The Momentum series, known for its spacious design and toy hauler capabilities, offers a range of models, each with slightly different dimensions. Generally, you can expect lengths ranging from around 38 feet to over 44 feet, depending on the specific floorplan. Widths typically hover around 8.5 feet, but always double-check the specific model. The height, including the air conditioning unit, is usually around 13 feet, which is important to remember when considering bridges and low-hanging branches. Now, let's talk about weight. Gross Vehicle Weight Rating (GVWR), the maximum weight the trailer can handle, is a critical figure. It varies depending on the model, but you can typically expect GVWRs from around 16,000 to over 18,000 pounds. You'll also need to consider the dry weight, which is the weight of the trailer without any cargo, water, or propane. This can range from around 12,000 to 14,000 pounds. Knowing both the dry weight and GVWR is essential for calculating your available cargo carrying capacity (CCC), which tells you how much weight you can add in terms of your gear, water, and personal belongings. Hitch weight, the weight the trailer places on your tow vehicle's hitch, is another key factor. It usually ranges from 2,000 to 3,000 pounds. Ensure your tow vehicle is rated to handle both the GVWR and the hitch weight of the Momentum you choose. Having a proper understanding of these dimensions and weights ensures a safe and enjoyable towing experience. Always consult the manufacturer's specifications for the exact measurements and weights of the specific model you're interested in, as these details can vary slightly. We will also look at the different floorplans in the next section to show how the different specs may vary.

Detailed Breakdown of Exterior Specs

Let's get even more granular and look at some specific examples. For instance, the Momentum 351M, a popular model in 2017, typically has a length of around 40 feet, a width of 8.5 feet, and a height of about 13 feet, with a GVWR of around 16,000 pounds. Its dry weight is usually around 13,000 pounds, and its hitch weight falls in the range of 2,500 pounds. In contrast, a larger model like the Momentum 399TH might stretch to over 44 feet in length, with a GVWR of over 18,000 pounds. While the width and height remain similar, the dry weight and hitch weight will naturally be higher. Remember, these are estimates, and the actual figures can vary based on options and modifications. Always refer to the sticker on the RV itself or the manufacturer's documentation for the most accurate information. These dimensions are not just numbers; they affect every aspect of your travel. You will have to consider the space you need when setting up at a campsite, the maneuverability when backing up, and the storage options available. Consider the garage area when thinking of a toy hauler. This is often the largest factor. The exterior construction of the 2017 Grand Design Momentum is typically robust, using high-quality materials and construction techniques designed to withstand the rigors of the road. Features such as a fully laminated sidewall construction, a strong frame, and a gel-coat fiberglass exterior contribute to the durability and longevity of the RV.

Towing and Handling: Taking Your Momentum on the Road

So, you've got your 2017 Grand Design Momentum, and you're ready to hit the road. Let's talk about towing and handling. Safety and a smooth ride are paramount. You will need a tow vehicle that's up to the task. Given the size and weight of the Momentum, you'll need a heavy-duty truck with a sufficient towing capacity, typically a 3/4-ton or 1-ton truck. Make sure your truck has the proper hitch receiver, rated to handle the weight of the trailer. A weight distribution hitch with sway control is highly recommended for a more stable and controlled towing experience. Before you hit the road, make sure to check your trailer tires for proper inflation, as this can affect handling and fuel efficiency. It's a good idea to perform a pre-trip inspection, checking the lights, brakes, and other essential systems. When towing, take your time and be aware of your surroundings. Allow for extra stopping distance and be mindful of the height and width of your RV when maneuvering. Always use your mirrors and be cautious when changing lanes or making turns. When backing up, get a spotter if possible, and take it slow. Proper weight distribution is essential for a stable and safe towing experience. Ensure that the trailer is level when hitched to your tow vehicle, and distribute the weight of your cargo evenly. Regularly check your tire pressure, and ensure your brakes are functioning correctly. With proper preparation and safe driving practices, you can enjoy a safe and enjoyable towing experience. Towing your Momentum is an adventure in itself, so taking care and being prepared is key.

Tow Vehicle Recommendations and Tips

Let's get specific on tow vehicle recommendations. The 2017 Grand Design Momentum requires a robust tow vehicle. Generally, you'll need a heavy-duty truck with a towing capacity that exceeds the GVWR of your Momentum. Popular choices include the Ford F-250 or F-350, the Ram 2500 or 3500, and the Chevrolet Silverado 2500HD or 3500HD. When choosing a tow vehicle, consider the engine size, transmission, and rear axle ratio. A diesel engine typically offers the best combination of power and fuel efficiency for towing. Ensure the truck has a properly rated hitch receiver, and a weight distribution hitch with sway control is highly recommended. Properly distributing the weight of the trailer is important. This is where the weight distribution hitch comes in. This distributes the trailer's weight evenly across the tow vehicle's axles, improving stability and reducing sway. Sway control helps to prevent the trailer from swaying, especially in windy conditions or when being passed by large vehicles. Regularly inspect your tow vehicle's brakes, tires, and other components, and follow the manufacturer's recommendations for maintenance. Before each trip, check the tire pressure on both your tow vehicle and your trailer. Proper inflation is crucial for safe handling and fuel efficiency. Pack smart and evenly distribute the weight inside your Momentum. Safety is the most important thing!. Don't exceed the GVWR of your Momentum or the towing capacity of your tow vehicle. Taking these extra steps will go a long way in ensuring a safe, enjoyable travel experience.
