If you are looking into refrigerated trailer rental, you should consider some advice from experienced people in the field. According to some research, the federal vehicle weight limits are 80,000 pounds gross vehicle weight, 20,000 pounds on a single axle, and 34,000 pounds on a tandem axle group. Individual states often have different limits. Using refrigerated trailers or reefer trailers can allow you to transport perishable goods, and possibly grow your business. Live floor trailer leasing services and companies can offer you full-service refrigerated trailer rentals, and maybe even provide a deal for first-time renters. You should consider if you want to use your trailer as a refrigerator or a freezer, and what the optimal temperatures for each setting are. If you want to use your own power source, you should consider what kind of breakers you have to be sure you are being safe. The refrigerated trailer should have two systems so that if the primary refrigeration unit fails, you will have a backup available while on the road. You should follow all the instructions provided with your rental unit closely, and contact professionals for help.
