What types of features should be recorded? Can you give me some examples?

The features field is open ended because the features depend on the type of asset. Any optional equipment that would make the asset different from other assets of the same year, make and model would be important to record. For a pickup truck, these options would include the type of engine, transmission, drivetrain and optional features like a tow package. For a tractor, these features could include the presence of a three-point hitch or powershift transmission or the number of hydraulic remotes.
