Price for what you get
A new full-size UTV commonly lands between $18,000 and $30,000. An inspected kei truck typically costs a fraction of that and includes an enclosed steel cab, heat and a real payload bed.
Payload and towing
Most kei trucks carry roughly 770 lb in the bed and tow light trailers. UTVs carry less in the box and usually need aftermarket accessories to match.
Road legality
Kei trucks can be titled and plated in most states. Many UTVs cannot leave private property without a county exemption.
Comfort and weather
Enclosed cab, windshield wipers, a heater and a locking door beat an open cockpit every winter morning.
Running costs
660cc engines regularly return 35–45 mpg. Parts are inexpensive and widely available online.
Where the UTV wins
Extreme trails, deep mud and rock crawling still favor a purpose-built UTV with long-travel suspension. For farm, ranch, campground, landscaping and municipal work, the kei truck wins on cost per hour.
