There are plenty of aspects to evaluate when deciding to purchase a single axle or a double axle trailer. First, you need to know is that the number of axles which will determine the number of wheels: a tandem trailer has two sets of wheels. Single axle trailers have fewer tires and brakes to maintain. So now you are questioning whether it is best to have a single or a double trailer and how those axles will impact the performances of the hauling weight.
Single Axle Trailers as the name implies, are easier to handle and makeover because they have only one axle on each end. The smaller size trailer consequently makes them more fuel economic that the tandem counterparts and often cost less to be purchased. Not only they are easier to park they are less expensive and more economical to tow. When you are purchasing a trailer you might as well think about the costs of the maintenance. In this case fewer tires result with lower replacement costs.
The biggest drawback is their smaller size, which means you can’t haul as much goods as with tandem trailers. The moving abilities are often smaller so you may be faced with certain limitations since there are only two tries to carry the weight. Although these are easier to park, you won’t feel very stable to ride on roads with bumps.
Tandem Axle Trailers is a trailer with two sets of axles, designed to handle an extra weight over any highway conditions. Tandem trailers are excellent for heavy loads as an ideal option at higher speeds. When properly loaded not only they are safer, they are also less prone to swaying. Often you have much better suspension, whatever you are hauling. By choosing a tandem model you could possibly tow more weight so the extra expense upfront is worth in the long run.
While the towing level is not so important in the first case here you need to pay more attention because if you tow unevenly only on one set of axles you are risking the life of your tires. If you carry light, your fuel economy will also suffer. If you decide to invest in a tandem trailer with more axles you should be aware that more maintenance with bearings, tyres and grease is required.
In the end there is no such thing as a right decision, everything depends on your needs and weight loads.
