What is the longest RV ever?

The SLRV Commander 8×8 Expedition vehicle is the longest RV ever. Here’s what makes this vehicle impressive in the RV world: 

  • Eight-wheel drive;
  • 480 horsepower under the hood;
  •  A12-speed transmission;
  • A 1000-litre fuel tank.

The Commander 8×8 is a real house … on 8 wheels and two floors, benefiting from a hard pop-up roof! A vehicle made for 8 people who can all sleep, the first for the parents, or the second for the children! Eight beds, therefore (and even 10 with an extra double bed), but also a huge kitchen, a bathroom and a living room for 10 people: downright!

This vehicle is a real tour de force and a feat in terms of layout. Based on the basis of a MAN TGS, the Commander 8×8 houses under its hood a 12.5 Diesel engine (you read that right!) Of 480 horsepower, mated to a 12-speed transmission and four differential locks: don’t throw it away anymore. !

Enough to go on a mission with the family in the most remote areas of the planet without fear of running out of fuel, with a 1000-litre tank (although on the consumption side, it must be strong). 

In addition, in the event of a big galley, the vehicle’s solar panels will allow you to operate the Commander’s lithium-ion batteries. For the record, this eight-wheeled monster was commissioned by a wealthy and anonymous businessman. Its price  Between $1 and $2 million, depending on the options selected!

Is it hard to drive an RV?

Experienced motorists tell us that it is not hard to drive an RV, however, for a newbie, it could pose a challenge. It is recommended that before driving an RV you familiarize yourself with its dimensions, as you must quickly get used to the vehicle and know in what space you can park or if a road is wide enough to fit on it.

High-end mobile homes can measure 1.90 m wide by 5 to 9 meters long, all depending on the model you choose.

Check that all internal parts are well fastened. Mobile homes have many drawers and compartments, which must be well secured to avoid unwanted accidents, likewise, check well that all doors are properly closed, that everything is well secured so that nothing causes harm to the driver and his passengers.

Everything that is inside the motorhome is usually heavy, such as the beds, the refrigerator, the kitchen, so, before driving the motorhome, try to balance the loads or weights, so that it does not wobble on the road, but remain stable. The latter is essential when the trip is to the mountain area

The bottom line

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.
