We crossed at Sweetgrass in 15. We overnighted in one of the last RV parks before the border so we hit the crossing early in the morning. Had one coach ahead of us, we were asked the usual questions and were on our way in 5 minutes. We had checked on what fruits,veggies,meat and other foodstuffs were prohibited so no problems at any of the crossings back and forth up north or returning to the lower 48. Eight crossings total. We had passport books not the auto cards and it was nice that they stamped them when entering at the top of the world border crossing at Poker flats.
