When you rent a truck you'll be responsible for driving yourself and making sure your things make it to your destination in good shape.
Truck rental companies usually offer multiple styles and sizes of trucks to suit the amount and type of stuff that will be moved. Carefully plan the amount of space you'll need, you don't want to cram everything together in an unsafe way. It could lead to damage, shifting, or difficulty unloading the truck. You also don't want to pay extra for space you'll end up not needing. The extra space could also result in shifting and damage if things aren't tied down securely.
You also need to remember that driving a fully loaded truck is very different from driving a car. The weight makes the truck difficult to stop suddenly and control in wet conditions. The truck also has a different center of gravity than a car so you need to pay special attention to the speed you're traveling at when you take tight turns. Be aware that many rental companies require experience from renters who wish to drive larger trucks.
Cheap moving trucks and discounts are usually the result of planning ahead. Many rental companies offer cheaper rates if you reserve trucks in advance. This is their way of ensuring a constant influx of customers. If you want to reserve a truck in advance you'll need to know the type of truck you need as well as the days you'll need the truck. If your trip is likely to take several days you'll need to plan for that as well. Most rental companies require you to pay for your own gas and might charge for miles driven as well since it impacts wear on the truck. Be sure you understand all costs associated with renting the truck before you sign an agreement.
Moving pets requires special care. If you'll be traveling through any extreme weather conditions consider paying extra for a climate controlled cab so your pets won't be injured by the heat or cold. Make sure your animals are packed in appropriately sized boxes designed for the
transport of animals. They should have adequate ventilation and access to water at all times. Make sure they're easy to get to and make frequent stops to check on them and allow them time to relieve themselves and stretch their legs. Moving can be a traumatic experience for pets so make sure they're as comfortable as possible.
Once you reach your destination you'll need to drop off the truck at the prearranged drop off destination. There may be multiple locations in one city so make sure you have the right one to avoid getting lost or drawing any late fees.
