A Kei truck and a John Deere Gator are the same thing except the Kei has like one or two more amenities as standard.
ETA: Actually depending on the Gator the Suzuki Carry is
arguably worse.
Comparing the 2025 Suzuki Carry Kei Truck to the 2025 John Deere XUV 875R Premium Cab Diesel the Kei produces about 64 horsepower and about 63 ft lbs while the Gator produces about 23 horsepower and unstated torque figures. The Kei uses a petrol engine with a 660cc displacement whereas this particular Gator uses a 4 stroke diesel with an 854cc displacement.
The Kei has a larger cargo bed than the Gator. The Kei's cargo bed is approx 79.2 inches long by 51.6 inches wide. John Deere does not give the full dimensions of the Gator on their website but they do give the cargo box dimensions which are 43.3 inches long by 54.8 inches wide. The Kei does have a dropside flatbed which is nice since that's a feature the Gator lacks. On the other hand the Gator has a dump bed and the Kei does not. HOWEVER, the actual rated weight capacities are in the Gator's favor, the Suzuki has a bed capacity of approx 900 lbs at most but are usually estimated to only be able to carry about 750 lbs safely whereas the Gator has a rated bed capacity of 1,000 lbs, so despite the larger bed of the Kei you can still carry near enough the same amount of cargo by weight but only if you really push it in the Kei. The towing capacity on the Kei from what I can see all hover around 1,000 lbs, the Gator has a rated towing capacity of 4,000 lbs.

CONCLUSION: Literally the only advantage to the Kei over a Gator is that the Kei can maintain road speed and so if you need to make a quick run to town it can do that faster than the Gator. (A lot of rural areas don't care about UTVs or ATVs travelling on the road or even being used on town streets so long as they're registered, before anyone brings up the question of legality. Many small towns in my area have signs that specifically state "all Town of [TOWN] streets are ATV routes unless otherwise posted") The Kei truck
does have a larger bed but the overall dimensions between the two means the cab actually isn't that much bigger and the Gator can seat three whereas the Kei can only seat two and the knee room is about the same. Any size advantage the Kei has is immediately undercut by it's whimpy carrying capacity and it can't tow to save it's life either so you can't offset the poor bed capacity with good towing efficiency, meaning that the Kei is only really good for bulky but low density loads, and even then a contractor will need to drop the tailgate and/or lower the sideboards in order for things like plywood, lumber, and sheetrock to lie flat. Which isn't a dealbreaker for me personally but for some contractors that's a serious problem. Really the only advantage to the Kei is that it's very cheap, this particular model sells for about 16,000 USD which is about half what the premium model Gator costs.
It is my ultimate conclusion and opinion that outside of an incredibly small niche THERE IS NO REAL MARKET FOR THIS TYPE OF VEHICLE IN THE UNITED STATES AND CANADA
