We use Tomcat Rodent Repellent, comes in a 1-gallon jug at Home Depot. Non-poisonous. Spray it around the camper sitting in the bed of the truck maybe once a month, twice a month around the engine compartment. (It will evaporate over time.) We used to see rodent activity in the engine area, don’t see it anymore. Never had an issue in the camper.
