Arrival flow · pull in to plugged in
Arrival Sequence
  1. 01 Pull in and park on the pad. Aim for approximately level to keep ram travel short.
  2. 02 Dump air. AIR DUMP wedged — nickel or sunglasses earpiece. Full procedure: Guide › Leveling.
  3. 03 Level the coach. RVA J-II panel — pads under the 3 rams, LEFT · FRONT · RIGHT to center the bubble. See Leveling.
  4. 04 Hook up 50 A shore power. Cord lives in bay D5. Pedestal breaker OFF while connecting, then ON.
  5. 05 Connect city water. City water inlet at the wet bay — D4.
  6. 06 Connect sewer. Wet bay D4. Keep the black and gray valves CLOSED until you're ready to dump.
  7. 07 Close blinds. Windshield privacy shade + front-cap shades; slide-out and bedroom last.
  8. 08 Verify shore power is working properly. Wait 30–45 s for the green EMS lights before switching on AC or any high-draw load. Rule: Electrical › No green, no AC.

Cook Camp

Outdoor kitchen · rugs, tables, grills, smoker · from bays D2 / D3 / P2
Where It Lives
Setup Order
  1. 01 Roll out the rugs and stake them down. Rugs from P2, rug stakes from D2. Everything else stages on top.
  2. 02 Raise the pop-up canopy over the P4 / P5 side for extra shade. Pop-up canopy from D3. This is the free-standing one — the coach's electric awning has its own procedure, see Awning.
  3. 03 Set out tables and benches under the canopy. From D3.
  4. 04 Assemble the Blackstone table + griddle in kitchen position. From P2.
  5. 05 Position the BBQ grill. From P2.
  6. 06 Set up the Green Mountain mini smoker; grab the pellet bag. Smoker + pellets from P2.
  7. 07 Set up the fire pit at a safe distance from the canopy. From D2.
  8. 08 Connect a grilling propane bottle to whichever unit you're using. Bottles live in D2. Snug hand-tight — no wrench on brass.

Awning

Coach electric awning · key-enabled · rocker in entry stairwell
Extend
  1. 01 Wind check. No wind now, nothing forecast. If either is uncertain, leave the awning in.
  2. 02 Ground clear under the awning path — furniture, string lights, kids.
  3. 03 Grab the RV key ring from the cupboard above the driver's seat. Insert the awning key and turn it ON. This enables power to the awning motor.
  4. 04 Entry stairwell — hold the rocker to OUT / EXTEND.
  5. 05 Watch both arms. If one catches, GENTLE shake and light assist to free it. Two more sets of hands ready. Never force.
  6. 06 Release the rocker at your desired extension. Turn the key OFF.
Retract
  1. 01 Clear everything under the awning — chairs, tables, cords, string lights.
  2. 02 Key ON.
  3. 03 Stairwell rocker — hold IN / RETRACT.
  4. 04 Assist the arms in as they travel. GENTLE shake if either sticks. Same rule: up to 3 people, never force.
  5. 05 Fully retracted — check both arms are seated flush against the coach.
  6. 06 Key OFF. Stow the key.

  3. 03 Press AIR DUMP down and wedge it held. Use a nickel or a sunglasses earpiece to hold the rocker — it's momentary.
  4. 04 Let ALL the air out. The coach lowers all the way to the ground.
  5. 05 Slide a pad under each of the 3 jacks. Use the T-handle with the hook (same compartment) to drag the pads into position.
  6. 06 Extend / retract LEFT · FRONT · RIGHT to center the bubble level.
Panel Lights
Stow Before Driving
  1. 01 Key to ACC, leveling system ON.
  2. 02 RETRACT all three rams all the way up.
  3. 03 Pull the pads; stow pads and T-handle in the D2 bay.
  4. 04 Confirm the RED light is OFF.
  5. 05 Release AIR DUMP. Let the bags re-inflate — coach rises to ride height.
  6. 06 System OFF. Drive only with the red light out and coach fully aired up.

Power Up
  1. 01 Connect shore power OR start the generator.
  2. 02 Wait 30–45 seconds. Don't touch any switches yet.
  3. 03 Watch the panel for the green lights = system settled and ready.
  4. 04 Only then turn on the roof AC or any high-draw item — microwave, water heater.

Generator

Cummins Onan Quiet Diesel 7500 · 7.5HDKAJ · 35 A 2-pole · 3 qt oil w/filter
Wet-Stacking Recovery Run
  1. 01 Confirm enough fuel for a 1–2 hour run under load. Rated 7.5 kW at full load burns roughly 0.7 gph diesel.
  2. 02 Turn the panel rotary switch to ON.
  3. 03 Press and HOLD Start / Preheat. Watch the red LED — that's the preheat glow-plug cycle. Hold 5–15 seconds; release when the engine catches.
  4. 04 Warm up 5–10 minutes at no load.
  5. 05 LOAD IT UP: both roof A/Cs on, water heater on electric, microwave running periodically. Target 4.5–7 kW draw (60–95% of rated). Under-loading is what caused the problem — solve it with load.
  6. 06 Run under load for 1–2 hours. Longer if it was severely wet-stacked. Listen: engine should settle from rough to smooth as heat builds. Watch exhaust: dark smoke should clear.
  7. 07 Cool-down: drop load to near zero for 2–3 min, then Stop.
  8. 08 Going forward: exercise the genset monthly at 50%+ load for 1–2 hours. Prevention beats cure.
Start / Preheat / Stop (from the coach panel)
  1. 01 Rotary switch to ON.
  2. 02 Press and HOLD Start / Preheat. Red LED on = preheat cycling. Diesel needs the glow plugs warm before firing. 5–15 seconds is typical, longer when cold.
  3. 03 Release when the engine catches. Let it settle 30–60 sec before adding load.
  4. 04 To stop: shed load, let it idle 30–60 sec (turbo cooldown discipline), then press Stop momentary.
  5. 05 Rotary switch to OFF when done.

Flat-Tow

2017 Cadillac Escalade 4WD · 2-speed transfer case (N + 4LO) · Blue Ox tow bar · manual battery cutoff
Hook Up & Go
  1. 01 Park level. Windows up, doors closed. Once power's cut you can't run the windows.
  2. 02 Set park brake. Start the engine.
  3. 03 Transmission to N (Neutral).
  4. 04 Transfer dial to 2HI, then turn toward N and HOLD 10+ seconds. N light blinks, then goes SOLID = transfer case in neutral.
  5. 05 Verify: shift to R, then D. Truck must NOT move. If it creeps, redo step 4.
  6. 06 Transmission to P (Park).
  7. 07 Engine OFF. Press START without the brake → ACC. Amber accessory light on. Take the fob with you.
  8. 08 Release the park brake.
  9. 09 Battery cutoff → OPEN. Confirm dead — dome light and horn off.
  10. 10 Connect tow bar, cables, lights, brake line — then run the Blue Ox check below.
Blue Ox Hookup Check
  1. Both arms fully extended and locked — pull coach forward a few inches, arms snap rigid.
  2. Every pivot and clevis pin has its clip or cotter pin — both ends.
  3. Safety cables crossed in an X, shackles threaded and pinned.
  4. Blue lighting cord plugged both ends — test brake, turn and markers.
  5. Breakaway cable clipped to the COACH, not the removable bar.
  6. Battery cutoff confirmed OPEN.
Unhook On Arrival
  1. 01 Disconnect tow bar, cables, lights, brake line.
  2. 02 Battery cutoff → CLOSED.
  3. 03 Set park brake, hold brake pedal, start engine.
  4. 04 Transmission to N.
  5. 05 Transfer dial to 4HI (or AUTO). N light goes off.
  6. 06 Shift to P. Confirm normal drive.

Valve internals — schematic
Replace The Valve
  1. 01 Shut water off at the pump AND the city inlet. Open the shower to bleed pressure.
  2. 02 Open the galley cabinet chase to reach the red / blue PEX runs. No dedicated shower panel — go in through the kitchen.
  3. 03 Pull trim, remove handles and escutcheons; unscrew and lift out the old Phoenix valve body.
  4. 04 Fit the new Phoenix PF213350 with SharkBite / PEX female adapters. PTFE tape on threads. Hand-tight, then a quarter-turn — do NOT overtorque the plastic fittings.
  5. 05 Charge the system slowly. Check both stems and every joint for weep. Cycle hot / cold a few times.
  6. 06 Re-fit handles, escutcheons, trim. Confirm no drip after a 15-minute soak test.
