Probably 15 years ago a co-worker was on vacation in California pulling a heavy 5th wheel with a Dodge 2500. Highway patrol pulled him over and weighed him. They let him go but told him if he had been a "local" they would have him unhitch and come back for the 5th with a suitable truck.
I have read on a local fishing forum that Texas highway patrol has pulled heavy 5th's over but I haven't heard or seen it first hand.
I've seen more than a few that needed to be pulled over.
