What can cause the pickup to rust?

Rust can have many different causes, but the most frequent ones are being exposed to humidity and/or salt, coming into touch with other metals (particularly iron), and not having enough protective coatings. The most frequent cause of pickup rust is likely to be road salt. Although it can be used to melt snow and improve traction on highways during winter, salt also corrodes automobiles. However, if you reside in a region that spends the year without winter or ice and doesn’t utilize road de-icing equipment when necessary, salt is not a concern — Phoenix wouldn’t have to worry about trucks rusting because of road salts. The presence of standing water is a significant factor in the rusting of trucks.

When water is left on a truck for a lengthy amount of time, the moisture degrades and eventually leads to rust. Be careful where you park as places that don’t have good drainage can encourage water build-up and result in rust on a vehicle. Parking at places where nothing can be found below to encourage stagnant puddles or floods that might collect if it rains will help to prevent this.
