03 — A diamond in the rough

A time capsule
to the luxury that was.

In 1990, Canadian Coach Inc. transformed an MCI MC8 shell into a rolling apartment — a $200,000 custom build in 1990's money. That's the equivalent of nearly half a million dollars today. Top-of-the-line everything. Not a home-built conversion. A real coach.

Our Dad bought it in 1994 for $175,000 and it became his retirement obsession. Through the late 90s he poured himself into it — a more powerful 8V92TA Detroit Diesel, new air bags, an automatic leveling system. Every system kept at the highest spec of its era.

Then life happened. A few trips out of Fallbrook between 2001 and 2005. Then it sat. From 2005 to 2018, the coach waited under the California sun while the world moved on around it.

In 2018 we turned the key. The 8V92 came back to life — no smoke, just that deep, good Detroit Diesel rumble. We drove it from Fallbrook to Oceanside, where it's been parked ever since, fired up and moved locally a few times a year.

Today it's a diamond in the rough. The paint is faded, gaskets need work, and it carries the honest scars of years sitting outside. But underneath it all is the same coach that cost $200,000 to build — polished stainless, real wood, top-shelf systems, a bulletproof drivetrain, and a soul.

This isn't a turn-key RV. It's a fixer-upper for someone who sees what it was and what it can be again — someone passionate about the vintage coach experience and willing to bring this old girl the rest of the way back.

"She was once magnificent. With the right hands, she will be again."

04 — Honest disclosure

What works. What doesn't.

The bus isn't perfect — it's been sitting for years at its current location. This is a work in progress, but the bones are solid and the drivetrain is strong. Here's the honest breakdown.

What works

  • Engine starts right away and drives without hesitation
  • Air brakes work fine — no issues stopping
  • Air bags & brakes function (no formal inspection beyond basic checks)
  • Wipers work
  • Headlights and tail lights work
  • Generator runs; powers interior house lighting and both roof A/C units
  • Both roof-mounted house A/C units blew cold air when last checked
  • Coach (dash) A/C blows air throughout coach — pump functions
  • Microwave lights up and functions
  • 12V starter batteries are excellent — only a few years old, well maintained
  • Tires (replaced before move) — no cracks, still look relatively new
  • Polished stainless siding looks amazing when cleaned up
  • Title current, registered, CA emission-waived

Needs attention

  • 12V house system in disrepair — wiring issues need to be addressed
  • No house batteries included (starter batteries are included and excellent)
  • Some window gaskets will need to be replaced
  • Paint is faded in many locations
  • Bumper chrome is peeling
  • Signs of water leakage inside the coach
  • Overhead cabinet at front has detached — needs to be re-attached & repaired
  • Coach A/C needs to be recharged
  • Some of the exterior marker lights are not working (some do work)
  • Plumbing untested since parked — all water systems worked when originally parked
  • Refrigerator & washer/dryer untested — worked when parked years ago
  • Nothing formally inspected beyond basic functionality checks

Sold as-is. Buyer should arrange a professional inspection. The drivetrain is strong and the build quality is genuine — looking for an owner ready to bring it the rest of the way back.
