Cat scale, DOT scale wts on the side of the.road, are really only.good until you fill up with fuel the next time. Put a.load of groceries in the tree trailer or truck.......Yes CAT will to a degree stand behind the weight you were on that day, but a day later....you're on your own! I personally see no.reason to.pay $20 @ a CAT scale when are least locally, there are DOT scales every 50 or so miles along the interstates, you can weigh for free any way you.want if they are not manned by CVEO's doing a job.
They do not care what the manufacture rating is frankly. All they care about is that you are under 20k per axle, or the lessor of 500lb per inch width of tire. Along with.a.paid for give that is MORE than what you weigh at that moment in time.
Reality is, OP will be legal with ANY trailer from an Leo standpoint. Civil court is another.factor. Along with warranty potential not covering if the over weight facto.comes.into.play.
