Called on a dually towing another truck on a trailer- passed me (I was doing 65) on a 4 lane mountain pass and he was weaving/swaying so badly I though he had gone over the bank - I was just following skid marks after I lost sight. Police met him at the next town. Some people are a danger to themselves and everyone on the road. You bet I'll call on those. I don't exceed the speed rating of my trailer tires or the limit - whatever comes first -unless it is dangerous to slow down. I admit 55 in cali is a challenge- at times I had to clock 5 over or be run over. Rage driving rv haters are everywhere now.
