Baseline Overland's GMC Yukon XL Denali Walkaround

Peter is the Owner of Baseline Overland. This is their family rig and the original Baseline platform truck. This previously impossible to outfit vehicle demonstrates his commitment to the Baseline philosophy of "Working hard for hard-to-outfit vehicles" by creating and encouraging production of a wide array of products for what once was an an almost impossible to modify platform.

Peter has modified his Yukon XL to fit his family's needs on and off-road from the inside and out. From suspension, armor, lighting, roof rack system, and storage solutions, this vehicle is ready for family adventure.

Peter has the 2007-2014 Suburban Roof Rack which allows him to have plenty of space for the ever changing gear, accessories and roof top tents all while looking great on his rig. He often runs an iKamper purchased from Altitude Industries and a large Pelican Cargo Box with a quick release case mount by The Mounting Company freeing up the interior from bedding, chairs, or other gear.



Peter is running a Chassis Unlimited Octane Winch Bumper and dual swing out rear bumperrock sliders from Rock-Road Outfitters, and ASFIR Skid Plates rounding out a full suite of products for these previously hard-to-outfit vehicles.

For suspension, Peter is using Icon Vehicle Dynamics 2.5" Coilovers with adjustable compression damping valves. The adjustable coil overs are set at 2.5" lift. He has Icon rear shocks, Dobinson Constant Load 2" rear lift springs to handle the added weight of the drawer system, swing out rear bumper, and weight of the 35 inch spare being positioned further behind the axle. Air Lift helper bags keep things level when towing. He uses the SDE shock delete kit to bypass the Denali AutoRide and Magneride systems. This setup has been treating him very well and handles everything from off road, to towing their small off-road trailer through those curvy mountain passes or shuttling kids to dance practice. 


On the front bumper Peter is using  the New Baja Designs SAE  Fog Lights in Amber and Clear in the fog pockets and a Baja Designs OnX6 Arc Dual Control 30 inch LED Light Bar in the center section. All of these lights are powered and controlled by Trigger Controller. 

In the rear bumper, a pair of Diode Dynamics C1R Triple Function Pod Lights handle Brake, Reverse and Running light duties. Simple installation and control is provided by the C1R 7-pin Dual-Output Trailer Wiring Harness.

Future plans include adding some Baja Designs S2's and S1's on the roof rack for scene lighting at the campsite.

Peter is running 17" Method Race Wheels 703s with BeadGrip technology wrapped with Goodyear Territory MT 315/70R17 (35" equivalent) while patiently waiting for the new 35 inch Milestar Patagonia A/T Pros to become available.

In the back of the Yukon XL is the new modular Drawer Kit which is level with the 3rd row seats when folded. This is where he organizes his off-road recovery gear, tools, jack, Viar Compressor, and first aid.


The stock 6L80 Transmission was rebuilt at ~230K miles. After a complete failure 3 months later in the far left lane of the 405, during rush hour, in Huntington Beach, during a 5,000 mile road trip, the transmission was replaced with a new unit. Recently the stock L92 (6.2L) engine was replaced with a Chevrolet Performance LS376/ 525 HP crate motor. The old long block is slated for a complete tear-down and rebuild to swap into their 1990 K5 Blazer. 
The truck also has a remanufactured front differential and 14 bolt semi float rear axle with an Eaton Truetrack and 4.56 gears. Other improvements include a larger transmission cooler, K&N Cold Air Intake, Jet Performance Throttle Body, Bosh injectors and Summit Racing ignition coils. 

Next up is a manual 2 speed transfer case swap!
