For a 2018 RAM ProMaster 3500 with under 50,000 miles, equipped with a 12-foot Super Lawn Trucks (SLT) all-aluminum/composite body, the estimated appraisal value is between $38,000 and $48,000. [1, 2]
While a standard 2018 ProMaster 3500 box truck might only be worth around $18,000–$22,000, the specialized SLT upfit adds significant professional value. These trucks are custom-built in Fort Valley, Georgia, and are highly sought after in the landscaping industry for their “mobile shop” capabilities. [3, 4, 5]
Value Breakdown
- Chassis Value (2018 ProMaster 3500): A low-mileage (under 50k) 3500 chassis alone is valued at roughly $18,000–$23,000 in the current used market.
- Upfit Value (Super Lawn Truck Body): The 12-foot SLT Eco-AL™ body system with a 2,500 lb ramp and specialized tool racks is a premium commercial asset. New, these integrated systems can cost significantly more, and used units with the body intact regularly list for $45,000+ when mileage is low.
- Mileage Premium: Most 2018 commercial vehicles have 100,000+ miles. Having under 50,000 miles puts this truck in the top tier of available used inventory, often commanding a 15–20% premium over average-mileage units. [4, 6, 7, 8, 9]
Key Appraisal Factors
- Specialized Ramp: The built-in 2,500 lb capacity loading ramp is a major selling point for landscape professionals, as it eliminates the need for trailers.
- Body Construction: The all-aluminum and composite construction by Super Lawn Trucks is corrosion-proof and lighter than steel, which preserves the payload capacity of the ProMaster 3500.
- Tool Organization: Built-in racks for trimmers, blowers, and hand tools increase “turn-key” appeal for buyers looking to start working immediately. [3, 10]
