Sumas Border Crossing in Washington State

We're down in California right now and are planning to head back to Canada in mid April.

Had planned on going up the coast and crossing back into BC at the Sumas Crossing. Was talking to a rv'er from BC today that said we would have a hard time crossing the border with our 45' Class A as it was to tight to get through.

Was curious if others have gone that route or should I be looking for a different crossing.

Thanks
