The MAXXTOW Dual Hitch Extension, Model 70070, is a towing accessory designed to provide two receiver hitches from a single tow vehicle receiver. This device allows for the simultaneous attachment of a trailer and an accessory, or two accessories, to a tow vehicle. It is specifically designed for users who need additional versatility from their vehicle's hitch system.

Function Description:

The primary function of the Dual Hitch Extension is to convert a single 2" x 2" receiver hitch on a tow vehicle into two separate 2" x 2" receivers. One receiver, the lower one with a collar, is designated for towing a trailer, while the upper receiver, without a collar, is intended for attaching accessories. This design allows for the use of a trailer and an accessory (such as a bike rack or cargo carrier) at the same time, enhancing the utility of the tow vehicle. The device is not designed for towing with the upper receiver. It is crucial to understand that this product is an extension and not a standalone hitch, requiring a pre-existing receiver hitch on the tow vehicle for installation.

Important Technical Specifications:

• Receiver Dimensions: The Dual Hitch Extension features two receivers, each measuring 2" x 2". This standard size ensures compatibility with a wide range of towing and accessory equipment.
• Maximum Weight Rating: The device has a maximum weight rating of 4,000 Lb. for Trailer Weight and 400 Lb. for Tongue Weight. The "Tongue Weight" refers to the amount of the trailer's downward force exerted on the hitch. It is critical not to exceed these weight ratings to ensure safe operation and prevent damage to the extension, tow vehicle, or trailer.
• Top Hitch Adaptor: The top hitch adaptor is explicitly stated as "Not For Towing." This reinforces the design intent that the upper receiver is solely for accessories and not for pulling a trailer.
• Hitch Pins Required: The installation of the Dual Hitch Extension and the attachment of trailers/accessories require 5/8" diameter steel hitch pins with R-Shaped safety clips. These pins and clips are not included with the product and must be purchased separately. The safety clips are essential for securely engaging the hitch pins and preventing accidental disengagement.

Usage Features:

• Installation: The Dual Hitch Extension is installed by inserting its shank into the tow vehicle's receiver hitch. The lower receiver (with the collar) must be in the downward position for towing. A 5/8" diameter steel hitch pin and R-Shaped safety clip are required to secure the extension to the tow vehicle.
• Trailer and Accessory Attachment: Once the extension is secured, both the towed trailer and any attached accessories must also be secured to the Dual Hitch Extension using similar hitch pins and R-Shaped safety clips. It is imperative that all safety clips are fully engaged to prevent dislodgement.
• Weight Distribution: Proper tongue weight is crucial for safe towing. The manual warns that too much tongue weight can lower the tow vehicle in the back, leading to traction, steering, and braking problems. Conversely, too little tongue weight can reduce rear wheel traction, resulting in instability, swaying, or jackknifing. For proper handling, tongue weight should be under 10% of the Gross Trailer Weight (GTW).
• Dynamic Loading Awareness: Users must be aware of "dynamic loading," which occurs when a load is dropped onto the Dual Hitch Extension or trailer tongue, causing a short-term excessive load. This can lead to damage, failure, and personal injury.
• Leveling: The trailer and the towing vehicle must be level before attempting to install the Dual Hitch Extension.
• Safety Chains: Safety chains between the towing vehicle and the trailer are always required, regardless of the hitch setup.
• Pre-Use Checks: Before each use, the Dual Hitch Extension, trailer hitch, trailer tongue, and receiver hitch should be checked to ensure all hardware is tightly secured. Any damaged or worn parts should result in the immediate discontinuation of use.

Maintenance Features:

• Regular Inspection: The manual emphasizes the importance of regularly checking the Dual Hitch Extension, trailer hitch, trailer tongue, and receiver hitch for any signs of damage or wear. This proactive approach helps identify potential issues before they lead to failure or accidents.
• Adherence to Ratings: Users are instructed not to exceed the maximum weight ratings specified in the manual or the rating of the lowest-rated component in the vehicle/trailer towing setup. This is a critical aspect of maintenance, as overloading can cause irreversible damage and compromise safety.
• Proper Storage: While not explicitly detailed, the general safety advice to "keep this manual (and your purchase receipt) in a safe place" implies the importance of retaining product information for future reference, including maintenance guidelines or warranty claims.
• Cleaning: Although not directly mentioned as a maintenance feature, keeping the work area clean and well-lighted during setup and use can indirectly contribute to better inspection and care of the device.

Safety Information and Warnings:

The manual includes comprehensive safety information, using standard safety alert symbols (DANGER, WARNING, CAUTION, NOTICE). Key warnings include:

• Eye Protection: Always wear ANSI approved safety goggles when working with the product.
• Hearing Protection: Wear hearing protection in noisy environments to prevent hearing loss.
• Foot and Hand Protection: Use safety shoes, hard hat, and work gloves as applicable.
• Appropriate Dress: Avoid loose fitting clothing or jewelry that could get caught in moving parts.
• Alertness: Stay alert and concentrate; never operate under the influence of alcohol, drugs, or medication.
• Work Area Safety: Keep the work area clean, well-lighted, and free of spectators, especially children.
• Vehicle Safety: Ensure the tow vehicle is turned off with the emergency brake on before installation. Chock trailer wheels to prevent movement.
• Body Positioning: Keep arms, feet, and legs away from under the trailer during setup, hitching, unhitching, or moving.
