This was one of my first thoughts as well - what the heck will ETI do if these tariffs come to fruition? It speaks volumes about my emotional connection to what is, essentially, a business not a charity or individual but I do feel very connected personally through my quite extensive and long-term communications with the ETI Team.
My second thought was - since the prices on the website are now solely in USD, if the CAD$ tanks (not necessarily a bad thing - there's silver linings there) would ETI not benefit from being paid for 80% of their inventory/builds in US$? It would mean price increases to the US to cover perhaps the difference in gain made in incoming conversion and tariffs on the outgoing but, maybe it would net out at nowhere near the 10-20% anticipated?
As for sourcing materials etc. in the US and paying in USD - I totally see how that might affect costs but, perhaps this would be a boon and boost to smaller Canadian suppliers, current or future, of materials. I know nothing but, I'd imagine that the overall cost of materials from the US might make up....15-20% of total cost? There's a huge manufacturing component - thankfully. This isn't an assembly-line product. Each RV is "built for us" and that, I would think, makes up a large percentage of the cost. And that cost is all Canadian.
Sorry - I'm answering this rather late in the evening and haven't given it really proper thought so shoot me down at will.
