Actually it's a bit of both - and neither. I looked into this extensively about a year ago when I started shopping for a new 5ver and a TV.
Let me start with cars... all three major manufacturers have reciprocal warranty agreements on vehicles purchased in the US and brought into Canada. Makes sense if you think about it it - many of the vehicles are actually built here in Canada. You MUST dig deeply to find this info on their warranty disclaimers on their websites.
Regarding importing RVs - not a problem doing so from the standloint of Canadian standards. You are required to obtain some documentation and a certification from the manufacturer. A bit of paperwork - but not difficult. Check out the Registrar of Imported Vehicles web site (
www.riv.ca).
Tbe difficulty is in the RV dealership industry. Unlike the tightly controlled automotive dealerships (i.e. GM or Ford), there is no requirement to service an RV that was purchase from another location - even though it is of the same brand. It does not matter that it is within the same town, state, province or country. I have been told boldly by dealers that they will not service a new RV that was purchased from any dealer other than themselves.
This attitude by RV dealers blows me away because anybody with half a brain knows that automotive dealerships make their bread and butter off of service, not sales. You would think tbat the RV industry would have matured enough after all these years (and with the advent of the internet) to move closer to the automotive dealership model of sales and service.
Just my two cents worth...
