Two types of frame-mounted tie downs. Two different anchor locations. One decision that depends on how your camper is designed to connect.
Truck camper tie downs are not one-size-fits-all. If you have been researching how to secure a slide-in truck camper, you may have encountered terms like "inboard tie downs," "outboard tie downs," "frame-mounted anchors," "in-bed anchors," and "turnbuckles" without a clear explanation of what makes them different. The terms are not interchangeable, and choosing the wrong system for your camper means buying hardware that does not match how your camper is designed to connect.
This article explains the fundamental difference between inboard and outboard truck camper tie downs, when each type makes sense, and how your camper's anchor point location determines the right system.
The Core Difference: Where the Camper Connects
The distinction between inboard and outboard tie downs comes down to one question: where does the camper connect to the truck?
Some truck campers are designed with connection points that exit the camper outside the truck bed. These campers use tie-down points located externally, along the sides or corners of the truck, outside the bed rail. This is the outboard approach.
Other truck campers are designed with connection points that access the inside of the truck bed. These campers use anchor points inside the bed that connect through the camper's internal anchor system. This is the inboard approach.
Both approaches work. Neither is universally better. The right choice depends entirely on how the specific camper is built.
What Are Outboard Tie Downs?
Torklift outboard tie downs are frame-mounted tie-down brackets that create external connection points outside the truck bed. They bolt to the truck frame rails and extend outward, providing tie-down points at the corners of the truck bed where turnbuckles connect the camper to the truck.
Outboard tie downs are commonly used with spring-loaded turnbuckles such as Torklift FastGun turnbuckles. The turnbuckle connects one end to the camper's external tie-down anchor and the other end to the outboard tie-down bracket on the truck. This creates a tensioned connection between the camper and the truck frame.
Many truck camper designs use this external connection method, and outboard tie downs remain the right solution for these campers.
What Are Inboard Tie Downs?
Torklift ApexAnchors are the inboard option: frame-mounted internal payload anchors that bolt to the truck frame and provide accessible anchor points inside the truck bed. Instead of creating external connection points outside the bed, ApexAnchors bring the frame connection inside the bed, where compatible campers can anchor through their internal anchor point system.
ApexAnchors are designed for truck campers and compatible payloads that use internal anchor points. Not every camper is designed this way. A camper that connects to external tie-down points cannot use ApexAnchors, just as a camper designed for internal anchor points cannot use outboard tie downs.
Side-by-Side Comparison
| Tie-Down Type | Where It Connects | Best Fit For | What to Verify | Torklift Example |
| Outboard tie downs | External points outside the truck bed. | Campers with external tie-down anchors that connect outside the bed rail. | Truck fitment, camper anchor location, turnbuckle compatibility. | Torklift frame-mounted outboard tie downs + FastGun turnbuckles. |
| Inboard tie downs | Internal access points inside the truck bed. | Campers with internal anchor point systems designed to connect inside the bed. | Truck fitment, camper internal anchor compatibility, anchor ratings. | Torklift ApexAnchors + FastGun Apex turnbuckles. |
Why Camper Anchor Location Matters
The camper manufacturer determines where the camper connects to the truck. If the camper is designed with external tie-down brackets that exit the camper along the bed rail, outboard tie downs are the correct system. If the camper is designed with internal anchor points that access the inside of the bed, inboard tie downs like ApexAnchors are the correct system.
Buying a tie-down system without first confirming where the camper is designed to anchor is the most common mistake we see. The system does not determine the camper design. The camper design determines the system.
How to Know Which System Fits
- Check your camper manufacturer's documentation for anchor point location (internal vs. external).
- Check the truck fitment using Torklift's Find Your Fit tool.
- Contact Torklift support if you are unsure. We can help confirm the right system for your truck and camper combination.
Both Systems Are Frame-Mounted Torklift Solutions
Outboard tie downs and ApexAnchors are both frame-mounted. They both bolt to the truck's frame rails, the strongest structural member of the truck. They differ in where the connection points are accessed (inside or outside the bed), but they share the same engineering principle: anchor the camper to the truck frame, not to the bed sheet metal or generic cargo hooks.
Factory cargo anchors, bed-mounted hooks, and generic tie-down loops built into the truck bed are not the same as frame-mounted camper tie downs. They are designed for general cargo, not for securing a dynamic load with a high center of gravity. Truck camper securement requires dedicated frame-mounted hardware.
Key Takeaways
- Inboard tie downs (ApexAnchors) create anchor points inside the truck bed for campers with internal anchor systems.
- Outboard tie downs create external tie-down points outside the bed for campers with external connection anchors.
- The camper's anchor point location determines which system is correct. Neither is universally better.
- Both systems are frame-mounted Torklift solutions. Neither relies on bed-mounted cargo anchors.
- Check camper anchor location and truck fitment before buying. Contact Torklift support if unsure.
Frequently Asked Questions
What is the difference between inboard and outboard truck camper tie downs?
Outboard tie downs create external connection points outside the truck bed. Inboard tie downs (ApexAnchors) create anchor points inside the bed. The difference is where the camper is designed to connect.
What are outboard tie downs?
Frame-mounted brackets that create external tie-down points outside the bed, used with turnbuckles for campers with external anchor connections.
What are inboard tie downs?
Torklift ApexAnchors: frame-mounted internal payload anchors that provide accessible anchor points inside the truck bed for campers with internal anchor systems.
Which system is better for my truck camper?
It depends on where your camper is designed to connect. Check the camper's anchor point location first. The system follows the camper design.
Are factory cargo anchors the same as camper tie downs?
No. Factory bed cargo anchors are designed for general cargo. Frame-mounted truck camper tie downs are designed for securing a dynamic load with a high center of gravity.
How do I know which system fits?
Check your camper documentation for anchor location, then use Torklift's Find Your Fit tool or contact support.
