No concerns about RHD in Idaho. Most mail routes are rural, and require the carrier to provide his own vehicle. When Subaru quit importing RHD wagons just for that purpose, it was a big blow to rural carriers. Now for newer vehicles all that is out there for purchase are Jeeps. Every carrier I know (I used to do that) hates them. Nothing but problems. Rural routes here are brutal on vehicles. New troopies would be much appreciated. My LJ78 worked fine, but any 25 year old rig will be a problem to keep going with a 90 mile stop and go route every day, many days in 4WD.
