Southwest Cruiser

1978 MCI 8 Custom Coach

The 1978 MCI 8 “Southwest Cruiser” is a professionally converted motorhome coach by Custom Coach Corporation, built new from the factory as a private motorcoach—not a retrofit. With Custom Coach production number 2401, this 40-foot, non-slide Prevost conversion offers timeless quality, thoughtful craftsmanship, and a rich ownership history. Having been in private hands for over 20 years, this garage-kept coach has logged approximately 175,000 miles and has never served as a seated passenger bus.

Mechanically, the Southwest Cruiser is powered by a Detroit 8V71 engine mated to a 5-speed Allison automatic transmission, with recent service highlights including new Firestone tires and steel rims (Dec 2024) and new house and chassis batteries (Nov 2024). The onboard Kohler 12.5kW generator (2,282 hours), dual Copeland A/C units, and comprehensive electrical upgrades ensure the coach is fully self-contained for road or campground use.

Inside, the coach offers a true residential layout with a Princess 4-burner range, double sink, microwave, refrigerator/freezer, pull-out pantries, and even a Perm-A-Pub automatic bar. The front living area includes a swivel chair lounge, convertible dinette, and dual TVs. A walk-in bathroom features a vanity, shower, and electric heat, while the rear lounge converts into a full-size 75″ x 54″ bed with built-in seating, closets, and wardrobe storage. Additional systems include central vacuum, CB radio, intercoms, dual inverters, and multiple wall and floor heating units.

Located in Nashville, TN and priced at $35,000, the Southwest Cruiser is an outstanding example of a true vintage MCI bus conversion, ideal for collectors, vintage RV enthusiasts, or anyone seeking a classic luxury motorhome with character and capability.
