Rules for Transporting Collection across State Lines

[sdmark777]

I might make a special trip with the German related handguns as seen here. But, none are worth loosing and even this small number might seem like too many to a check point inspector. I really don't want to do a bunch of small trips. I have never taken a large box truck full of possessions across state lines. I worry they will want to go through all the guns if they figure out I am transporting firearms. Anyone with experience going through the large truck side of the check points?
