- are built with heavy and durable materials,
- have safety features such as engine brakes,
- offer a better view of the landscape and the possibility of monitoring traffic flows more easily,

How difficult is it to drive a 40 feet trailer?
40 feet trailers are not the easiest to drive motorhomes. You must take into consideration the dimensions of the vehicle, besides the usual precautions.
Travelling with an RV is a unique experience as it provides a fantastic feeling of freedom. But driving a car that pulls one of these houses on wheels is not trivial.
Differences in the vehicle’s response to acceleration, braking and cornering speeds due to the extra weight and increased aerodynamic drag make it necessary to drive particularly cautiously.
How to choose the size of your trailer and why it matters
The best size trailer to buy will depend on your needs and expectations: How many people are going to travel with the RV? Are you going to use it often enough or just for a few weeks/year? How much space do you actually need and what can you sacrifice?
The trailer or motorhome measurements can affect you on a day-to-day basis, so it is very important to know exactly the length of the vehicle because when passing through certain narrow places, tunnels or tolls, we will have to be safe to avoid unwanted accidents.
It is also essential to know the dimensions when parking on public roads since the motorhome must be correctly parked without invading more space than it should or could penalize us. As is logical, a smaller vehicle will allow us to manoeuvre and circulate more comfortably in confined spaces.
We do not all travel in the same way, nor do we like to visit the same places, so we must take a moment and think about the type of destination we want to reach. Obviously, those travellers who like to always use the best roads and go from area to area will have no problem driving a larger vehicle.
However, if you are one of those who like to get on more complicated roads and reach inhospitable destinations, you should take a good look at the heights of your future travel companion, because despite the fact that with this you may lose some habitability, in return you will enjoy without problems of your most desired destinations.
On the other hand, each one must also be aware of their driving skills because, although driving a motorhome does not entail any difficulty, its size can make us suffer more than desired, especially if we are not a little skilful. In this case, choosing a more compact vehicle will allow you to enjoy your vacation smoothly.
The bottom line
The size of your trailer matters, there is no lie to that. However, we consider that the layout of the motorhome may count more, especially when it comes to long-term living.
