If you have a VIN number and it is in shipment... just be patient. "on the truck" is simply a generic statement that it is on the way, as most of them are shipped by rail and only on a truck for the last local miles to the dealer.
Transit time varies, depending on the distance between you and the factory of origin, and also the factory. And Weather is certainly a factor right now will slow things down.
Example: June, Alliston Ontario as the assembly plant - to Northern California dealer, in good weather conditions takes about 10-14 days. Bad weather and all bets are off. When I looked up my 2017 transit manifest... it shipped first by ship to New York, then it went by rail to California, and then by truck to my dealership. This was when many trim/color options were in short supply, so even in 2017 we were buying CRVs that were allocated to the dealer, but not yet arrived. At that time the dealer would not take a deposit until they had the formal allocation (and a VIN for each vehicle). It's a bit different today, but the shipping methods and routes have not really changed from the factories.
and NO, you cannot go to Ontario and drive the vehicle or a truck on it's way to your dealer. 1) you are not licensed to do so. 2) it's an international shipment when it comes from Ontario to the US, so you have further requirements. 3) you don't own the vehicle yet, Honda does.
My suggestion: you have to pay the destination charges for the shipping and dealer prep on top of your MSRP anyway. Get your moneys worth and let the system do what it does.
