One time with my poor wife we detoured off the interstate around a major accident. She points to the right and says that was the truck route...me keeps going cause the car GPS had said so. Got to a low overpass RR and had to backup that red rigg and a 49' race trailer for 3 blocks in a small town. Embarrassing! Should listened to her and got a truck GPS right after that. We treat ours like a truck when we travel in it which has been a lot.
