They probably wouldn't have to be exactly lined up. Let's say you have a "cab" unit (receiver) that attaches to the back window in the cab. Then, a display up by the driver that the cab unit communicates to, to relay the information. That link could be wired, RF, whatever.... it sounds like your customer just doesn't want to have a wired unit between the truck and trailer. Then, I think you could align the cab unit and the trailer unit across from each other close enough that you could get the information (except during turns). I mean really, how much information are you really needing to transfer? It doesn't sound like much.
Here's another take on the touch memory (I-Button). Did you know that Rider Truck stores maintenance records for their trucks on I-Buttons? You rent one in Florida, drive it to California. At California, the pull up the service records on the I-Button and see what needs to be done next. Have a wand in the cab for the driver, when he gets out, he touches the I-Button on the trailer that transfers the trailer info to the wand. Driver hooks up the trailer, gets back in the cab, LCD displays the trailer info for the driver. The wand part is already a product. Our guard at work has one, there are check points through out the building. Once he's back to the office, he sets the wand in the cradle and it downloads all of the checkpoints. Kind of a check on the guard to make sure he's making the rounds. Just another idea.
