There are a number of different vehicles that fall under the term 'motorhome'. They vary in size and cost, but some include: campervans, low profile, micro motorhomes, American-style RVs, coachbuilt or overcab, and van conversions. The cost of your motorhome insurance will vary greatly depending on lots of factors, such as which features you choose or what level of cover you need. As with all motor vehicle insurance, you will be expected to take out at least third party only (TPO) insurance by law. You can decide to extend this to third part, fire and theft (TPFT) or fully comprehensive.
