About this file

Written by GovTribe AI · Sep 26, 2025

This document is a Vehicle Data Sheet for the Iowa Department of Administrative Services (DAS) Fleet Services, soliciting bids for 2026 Model Year Heavy Duty Trucks (HDT) RAM 4500 and 5500 chassis or equivalent. The procurement covers four vehicle specification groups: HDT 1 (Standard Cab 4500 Series 4X4), HDT 2 (Crew Cab 4500 Series 4X4), HDT 3 (Standard Cab 5500 Series 4X4), and HDT 4 (Crew Cab 5500 Series 4X4). The state will allow manufacturers to bid 2025 model year vehicles if 2026 model pricing and availability by 12/1/2025 can be demonstrated, with no distinction made between model year pricing when evaluating the lowest bid.

The bid requires detailed vehicle specifications including minimum gross vehicle weight ratings (16,000-18,000 lbs), specific wheelbase lengths, cab configurations, engine options (base V8/V10 or turbocharged diesel), and numerous standard features like power windows, air conditioning, Bluetooth, and safety systems. Dealers must submit electronic copies of the Vehicle Data Sheet in Excel format, completed RFB Criteria document, and insurance certificate. Additional options can be priced, including engine upgrades, special packages (snow plow, ambulance prep), and suspension enhancements. The document allows for pricing of delivery costs and provides flexibility for dealers to customize their bids within specified parameters.

Vehicle Specification Worksheets for Heavy Duty Chassis

This Vehicle Data Sheet will be used by the dealer to calculate their cost for each of the vehicle items they intend to bid. Please notice the tabs along the bottom correspond to the outline pictured below. This provides an outline of the items that are being bid in this Vehicle Data Sheet. The price located in the yellow highlighted field in each specification will be considered the dealer's final price submission for each respective vehicle specification.

Once the dealer has entered all the pricing information into this Vehicle Data Sheet, the Dealer will submit one electronic copy of the Vehicle Data Sheet in Excel format. Dealers will also have to submit one electronic copy of their completed RFB Criteria document and insurance certificate with their bid.

For manufacturers who have had or are soon to have a 2025 to 2026 model changeover, the State will allow the manufacturer's dealers to bid the 2025 model year vehicle in this bid if the dealer can produce pricing for the 2026 model and the 2026 model will be available to order no later than 12/1/2025. No distinction will be made between model year pricing when determining the lowest price bid per vehicle category.

All vehicle specifications are designed for single vehicle pricing.
