I am in an unusual position of having sold my house and I don't get my new house till 27th August. My motorhome insurance renewal is due 1st August. We normally tour for 18 weeks plus, so we are happy to do that while we wait on the new house. Informing the insurance company of a care of address at my daughters . We were informed that when at my daughters between campsites we couldn't sleep overnight in the motorhome as that would be considered staying full time in the van. I asked what the difference was as we normally visit and use the motorhome. The answer is we don't have a house of our own! They state all policies are the same. I can't find where in the policy it states a time limit or a voild if you sleep in your motorhome at your home address, but the operator stated that it was standard on all policies. So be careful how you word any claim resulting in your own drive.
