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 on the roof rack freeing up the interior from bedding, chairs, or other gear.

Peter is running a Chassis Unlimited Octane Winch Bumper and a dual swing out rear bumper. He is working with a manufactuer to develop rock sliders for these hard to outfit vehicles.

For suspension, Peter is using Icon Vehicle Dynamics 2.5" Coilovers with adjustable compression damping valves. The adjustable coilvers 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 large rear bumper and extra weight behind the axle along with Air Lift helper bags for towing and heavy loads. He uses SDE shock delete kit to remove 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 curvey mountain passes or shuttling kids to dance practice. 


On the front bumper Peter is using a mix of Amazon specials, but plans to upgrade to a full array of Baja Designs or Diode Dynamic lights for the center section and the New Baja Designs SAE  or Diode Dynamics SAE lights in the fog pockets. All of these lights are powered and controlled by an 8 gang switch and relay. Future plans include adding some Baja Designs S2's and S1's on the roof rack for scene lighting at the campsite. 

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

In the back of the Yukon XL is the new modular Drawer Kit which allows them to have two drawers, or a single drawer and a pull out cooler/ fridge area. This is where he has all of his off-road recovery gear, tools, 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, in the middle of 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 tranmsission cooler, K&N Cold Air Intake, Jet Performance Throttle Body, Bosh injectors and Summit Racing ignition coils.
