A spare trailer tire is standard, according to Null. “On one trip, I blew out a tire, so I just pulled off to the side, put on the emergency flashers, and changed the tire. Otherwise, it’s been pretty uneventful travel.” But he always stops for gas before he absolutely has to, and when he does, he checks everything to make sure nothing is broken or loose. “Once, I discovered a bolt on the jack plate had broken from too much bouncing on rough pavement,” Null explains. So, it pays to take a moment for a quick inspection.
