How to compare SuperTruss extension options by length when your overhang, clearance, and ratings decide the right choice.
When truck camper owners start comparing SuperTruss extensions, the length range can feel like a menu to pick from. It is better understood as a set of options matched to specific measurements. This guide explains how to compare SuperTruss product options across the 21 inch to 60 inch range, and why the right length always comes back to your camper overhang, trailer clearance, and the current rating chart.
As a national online retailer and towing equipment provider, Torklift Central helps you narrow the length options down to the one your measurements and ratings support.
How SuperTruss Length Options Are Meant to Be Compared
SuperTruss extensions are offered in a range of lengths so truck camper owners can match reach to their setup. There are several lengths available, ranging from 21 inches to 60 inches. The weight ratings are dependent on the length of the SuperTruss. See table below for reference:
| Capacities (Weight Carrying) | Capacities (Weight Distributing) | |
| Length | Tongue Weight / Pull Weight (lbs) | Tongue Weight / Pull Weight (lbs) |
| 21" | 750 / 7,500 | 1,400 / 14,000 |
| 24" | 750 / 7,500 | 1,400 / 14,000 |
| 28" | 750 / 7,500 | 1,200 / 12,000 |
| 32" | 650 / 6,500 | 1,200 / 12,000 |
| 36" | 650 / 6,500 | 1,200 / 12,000 |
| 42" | 600 / 6,000 | 1,200 / 12,000 |
| 48" | 600 / 6,000 | 1,200 / 12,000 |
| 60" | 500 / 5,000 | 1,000 / 10,000 |
Why the Right Length Starts With Camper Overhang
Your camper overhang is the distance the camper extends past the truck’s rear frame. It is the single biggest driver of how much reach you need. A modest overhang may only call for a shorter extension, while a longer overhang may require more reach to clear the camper and present the coupler.
Measure overhang carefully before comparing options. Measure from the face of your hitch receiver to the end of the truck camper bumper to identify the part number you need.
Why Longer Does Not Mean Better
It is a common assumption that a longer extension is the safer choice. In reality, extension length affects leverage on the system, and ratings are tied to specific lengths and configurations. Choosing more reach than your measurements call for does not make the setup stronger. It changes how loads act on the connection.
What to Measure and Confirm Before Ordering
Before ordering, measure camper overhang and trailer clearance, confirm the SuperHitch that fits your truck, and confirm loaded trailer weight and tongue weight. Then confirm the SuperTruss length that is compatible with your truck and camper set up. Remember that no extension increases your truck’s factory towing capacity and the lowest-rated component controls.
