    RAM 3500 BUILDS
    RAM 3500 Mega Cab Longhorn Limited — FULL Stage‑2 Walkaround (Custom Canopy, Rooftop Tent, Beer on Tap!)

We’ve built some big tourers—but this RAM 3500 Mega Cab Longhorn Limited might be the most complete, no‑compromise setup we’ve delivered. 

Stage‑2 adds a fully custom Concept Canopies fit‑out, reinforced rack with an ARB electric rooftop tent, huge on‑board water, smart electrics, twin compressors and yes… beer on tap. 

Up front: color‑coded two‑tone (factory bronze + PXJ black), Outback Kitters Pre‑Runner bar, Baja Designs LP9 driving lights, and a Carbon 15,000 lb winch. 

Underneath: a Carli Dominator 3.0 suspension package dialled for real weight and long corrugations. Rolling stock is Method 323 18x9 +12 with Yokohama Geolandar G016 35x12.5R18 and color‑coded flares for clean coverage.

If you want a go‑anywhere, live‑anywhere HD truck that can leave the van at camp and keep the family comfortable for weeks, this is your blueprint.

00:00 Intro & what changed from Stage‑1
00:46 Paint, two‑tone theme & chrome delete
01:28 Front bar: Outback Kitters Pre‑Runner + lighting package
02:52 Winch setup & isolation / controller routing
04:12 Wheels, tyres & color‑coded flares (fitment logic)
05:48 Suspension: Carli Dominator 3.0 (why big‑bore matters on heavy tourers)
06:40 Longhorn interior & LHD→RHD conversion notes
07:21 Reinforced rack + ARB electric rooftop tent (push‑button demo)
08:56 Why we chose a lightweight, premium custom canopy
09:51 Driver’s side: storage, drawer fridge, lighting & controls
12:07 Rear: plugs (12‑pin, Anderson), cameras, trundle drawer, ladder & roof storage
13:33 Boat‑on‑roof considerations & tent clearance
14:13 Passenger side: ARB twin compressor + 4‑tyre inflation hub
15:43 The kitchen: induction cooktop slide, dimmable work lights, beer on tap & ice
18:00 Dual drawer fridges (fridge/freezer) & pack‑down
19:09 Wrap‑up: who this build suits & next steps

Build Sheet (Key Components)

Front End & Protection
Outback Kitters Pre‑Runner front bar
Baja Designs LP9 (driving combo) + auxiliary corner floods
Carbon 15,000 lb winch (isolator in bay; remote + hard‑wire extension)
Camera & sensor relocations retained and calibrated

Driveline, Ride & Handling
Carli Suspension Dominator 3.0 kit (3.0" shocks with remote reservoirs)
Additional rear leaf added (3,500 platform) for constant canopy load

Wheels & Tyres
Method 323 | 18x9 +12
Yokohama Geolandar G016 | 35x12.5R18 (1800 kg load rating)
Color‑coded “extend” style flares for coverage

Roof & Sleeping
Reinforced rack system
ARB electric rooftop tent (push‑button open/close)
Side down‑lights (white/amber; dimmable)

Canopy (Concept Canopies)
Lightweight, premium custom shell, two‑tone to match cab
Central locking on doors & bins
Rear ladder, trundle drawer, top storage cases
Large under‑canopy water capacity (vehicle used to refill van off‑grid)

Air, Power & Comms
ARB twin compressor with manifold & 4‑tyre inflation hub (inflate all corners from one point)
Dimmable internal/external LED work lights (white/amber)
Vitro‑style power management screen + AC outlets & 12V/USB everywhere
Dual drawer fridges (run as fridge/freezer)
Induction cooktop on locking slide with fold‑down support
Beer on tap + ice machine (because… priorities)

Towing & Rear I/O
12‑pin trailer plug, Safety Dave camera input
High‑current Andersons (charge‑while‑driving & direct feed)
Gen‑Y hitch combo scheduled for final fit

Why this spec works
Touring reality, not theory: Heavy canopy, rooftop tent and water need shock volume and thermal headroom—hence Carli 3.0s.

Real‑world lighting: Amber up front for wet/misty nights; white up top for clear highway runs.

Fast air‑up: Twin compressors + 4‑tyre hub = less time in the dust.

Camp speed: Push‑button tent, induction cooking, huge water and dual fridges keep set‑up/pack‑down quick—and spirits high.
