US/Canada NEXUS restrictions for trailers????

PNWtabber

Looking forward to the opening of the U.S./Canada border 
Does anyone know if NEXUS card holders can use the NEXUS lane traveling between the U.S. and Canada if they are pulling a trailer?

I am a U.S. citizen and long-time NEXUS card holder, but new to trailering.  I can't find the booklet of rules I was given when I originally got my NEXUS card and can't find the information online.  I don't recall, off-hand, ever seeing a trailer in a NEXUS lane.  I just sent my passport in for renewal, but they are taking 3-4 months to process right now, so all I have is my NEXUS card.  Wondering if I can use the NEXUS lane or if I need to use the regular lanes.

@PNWtabber, I do not believe it specifically answers your question, but this article may be of interest to you or others planning a trip with an RV from the USA to Canada when the border opens up:
