Diesel motorhomes are more fuel efficient than petrol motorhomes. Which can make those long trips across the country much cheaper if you account for the fuel only. So if you plan on travelling to the ends of the Island, or across the English Channel to the ends of the Continent, then a diesel may be your best option.
However, the UK government wants to phase out diesel vehicles in the not-too-distant future to help the fight against climate change. From 2035 there will be a ban on the sale of diesel motorhomes. It’s a tricky situation to talk about, but there can still be a great deal to benefit from buying a diesel motorhome in 2021. If you’re unsure what to do, you can always get help by asking a motorhome expert.
