We are currently testing units built by Dill Controls. If they test out to our satisfaction, plans are to offer them as an option on new trailers as well as an add-on through our Parts Department. They will be available in Single and Tandem versions. Installation of the valve stem and transmitters will need to be done at a tire facility for add-ons. Pricing will be in the $300 – $375 range, depending on single or tandem application.One unit is making a trek to the West Coast soon and we will have a better grasp on functionality, although the early testing we have done has been good. Should have more to tell in mid-May.
