Depends what border crossing we go through either way. Sweetgrass easy and straight forward for many years, just one "I've got a badge attitude woman" once coming back into Canada that wouldn't believe hubby and I hadn't bought even a shot glass on a brief trip to vegas for a warm up one easter. Every other time coming back North we get couple questions and "Welcome Home", which we love to hear on our return.
Normally heading south into Montana those Border agents are generally OK with sometimes pull over and bring in tomatoes, or eggs or take it at the window and discard = different item every time, so now we take very little and shop in Great Falls after crossing.
Crossing South through BC though, a whole different story and avoid it like the plague - sniffer dogs put on board, making us leave our rig and searching without our presence although we requested to remain which unnerved us as to why they wanted us not to see what they were doing to our property.
Sask' small border crossing headed north we think agent was very lonely and had only seen 7 crossings in the week and they were all on that day, so the motorbikes in front of us were all made to take out everything in their boxes, and then we had the full inspection (took over one half hours to get through what in Sweetgrass would have been 7 mins absolute tops.
Quebec crossing back into Canada wonderful easy and quick in the couple of times we've come through from Florida back home.
It really is luck of the draw, on who you get, who they are trying to impress, and on what day, same with airports. Some confiscate your lunch sandwiches but the majority aren't phased by them when flying No logic, rhyme or reason sometimes to what they do or how they act.
