2003 Custom Motorhome / Tiny Home Freightliner MT55 Cummins Allison

2003 Freightliner MT55 Custom Tiny House / Motorhome Conversion

📍 Harleysville, PA

$19,000 OBO

One-of-a-kind custom tiny house, motorhome, or mobile business built on a commercial Freightliner MT55 chassis with a Cummins diesel engine and Allison automatic transmission.

I've tried to describe the vehicle as honestly and accurately as possible. If you have questions about any feature or system, please ask.

Originally a Snap-On truck, it has been converted into a spacious motorhome with approximately 176 square feet of living space. I recently purchased a home and no longer have the time to finish the project.

This is not a brand-new turnkey RV. It is an older custom conversion that is best suited for someone who appreciates unique builds and understands that older vehicles and custom projects require maintenance, finishing work, and occasional repairs.
