18 months outside UK

I would have thought that house vacancy is unlikely to be an issue if you are going to be away for so long. Either you will have sold up or rented the house out for the period of absence. I don't think many people would contemplate leaving their house unoccupied for 18 months or more.

Hi does anybody in this string know of a company/broker who can provide motorhome insurance for a UK registered motorhome, when its in Canada and the USA.

Thanks in advance 

Try Clements Worldwide cover.

I insured my car upon arrival in the USA through the Triple A.

Have you read all the blogs and travel reports on line from others shipping motorhomes across the Atlantic who have gone before you ?  They often explain the insurances and travel arrangements they used.

Have a look at Tread the Globe on u tube, they took their van to US and Canada and it wasn’t as straight forward as you may believe

Yes I have unfortuantely, and things have changed a little over the last 12 months. Thum insurance who the majority of people have used in the past have recently changed their policy. At the moment they aren't able to insure any vehicles in Canada. The will insure our motorhome when it's in the US, but we wish to travel in both countries. We have found one other insurer, but they won't insure against any 3rd parties claims who might be involved in the same accident. We would need 2 different insurances provided by different comapnies, they're are not cheap individually or together and could lead to all manner of issues if we ever had to claim. So as it stands we haven't found 1 company that will insure us. (I have asked Clements today, but haven't as yet had a reply). I have also already had an email conversation wth Marianne from Tread the globe, they used Thum too. 

Thum are hoping to be able to cover vehicles in Canada at some point in the future, bust as of today, it isn't an option.

Please keep forwarding your suggestions.
