Careful driving at all times is the way we should be doing things, but there are some things we do where the risk factor goes up. Overtaking slower vehicles, a perfectly legal activity unless otherwise indicated (like unbroken line markings), is one of those things.
Things to consider when overtaking with a motorhome
The majority of motorhomes are much heavier than the average car, but unlike trucks, on which many motorhomes are based, they are not driven by professional drivers — that’s not a slur on anyone’s driving ability, just a fact. When overtaking, the weight factor is certainly something to keep in mind.
Another is that, apart from some motorhomes and chassis imported from the USA, many are powered by European turbo diesel engines with capacities of around 2.3–3-litres and low relative horsepower ratings. It’s more than adequate in most situations but not if rapid acceleration is needed in a short time. When overtaking, these matters need to be taken into consideration.
