Build a Gladiator JT Overlander
The Gladiator JT is arguably the best factory platform for overlanding. The 5-foot truck bed provides purpose-built cargo space that no Wrangler can match, and the longer wheelbase provides more stable highway driving under load. This guide focuses on leveraging the Gladiator bed as the core of your overland setup with a bed rack, storage system, and camp amenities that make multi-day trips comfortable and organized.
Bed Rack and Tent System
The truck bed is why you bought a Gladiator for overlanding. A bed rack mounts above the bed sides and provides a platform for a rooftop tent while keeping the bed floor accessible for gear storage. Look for a rack that does not require drilling — most quality options use stake pocket mounts. The rack should support at least 600 lbs static load for tent occupants and 200 lbs dynamic load for driving. Pair the rack with a rooftop tent that fits the bed width (approximately 60 inches). Clamshell-style tents offer faster setup than fold-out styles but cost more. A tonneau cover over the bed provides weather protection for gear stored below the rack.
| Component | Why | Price Range |
|---|---|---|
| Bed Rack (stake pocket mount) | No-drill, holds tent + gear | $400 - $1,200 |
| Rooftop Tent (2-3 person) | Sleep comfortably, fast setup | $800 - $2,500 |
| Tonneau Cover | Weather protection for bed gear | $300 - $800 |
Suspension for Loaded Travel
The Gladiator rear suspension is tuned for occasional payload, not constant heavy loading. When loaded with a rack, tent, gear, and water, the stock rear springs compress noticeably. A 2 to 2.5 inch lift with medium-to-heavy rate rear springs maintains ride height under load and prevents the rear from sagging. Upgraded shocks improve ride quality and reduce body roll when cornering with a high center of gravity (rack + tent). Consider adjustable-rate springs or air bag helpers if your load varies significantly between trips.
| Component | Why | Price Range |
|---|---|---|
| 2-2.5" Overland Suspension Lift | Heavy-rate rears for payload | $1,000 - $2,500 |
| Helper Air Bags (rear) | Adjustable support for variable loads | $200 - $400 |
