I appreciate everybody's replies so far.
According to the dealer, as far as taxes it is exempted in BC as a result of the Free Trade Agreement, and I would just have to pay the state sales tax - which is zero in MT.
I looked up the MT registration requirement for a slide in camper. There is no registration for these campers built after 1991, but it has to be titled in MT. There are minimal costs to do that. Also, in MT, the titling and registration is done in the county courthouse in which we reside - no need to do it through the state DMV. You simply walk in, process a bit of simple paperwork, pay a small fee, and walk out. The whole process normally takes just a couple minutes. Just one of the reasons I like Montana.
I have gone to the Border Services website, and done a google search of importing a truck camper into the US - both of which I did before posting here, and,after going through many pages of regulations, I'll be dogonne if I could find anything of relevance - or anything that I could understand at least!
And lastly, I am not going to try smuggling anything into the US. Some days I might be tempted to leave my wife with the border patrol, but not my new truck camper!
