RV Description

2009 International Durastar 4400 Custom Heavy-Duty Motorhome Conversion


After trying dozens of motorhomes, which were poorly constructed and hard to drive, unless you pay over a half million dollars. I chose to build one, focusing on safety and durability. I employed a technician who had a lot of experience in motorhome, with whom we worked together for three years to convert an International Durastar Commercial Chassis. Beside its safety and durability, it feels you can drive it with a small finger. As my age isn't friendly on the road, I hope it can go to the right person. The price is negotiable. 


Engine: International DT466 Turbo Diesel, 300 HP

Transmission: Allison 5-Speed Automatic

Mileage: ±80,000

$140,000 invested— price negotiable


Built for Endurance

Originally a 2009 International Durastar 4400 (non-DEF model), this commercial-grade truck was carefully converted into a 32-ft Class Super C motorhome in 2016. It's an all-electric, no-propane build ideal for East Coast travel and tunnel compliance and delivers unmatched durability, safety, and functionality.
