Just some info about "rules of the road" out of the Colorado Drivers Handbook.
Merging: You must yield to all vehicles on that roadway. Do not merge if another vehicle must slow down for you.
Entering the Freeway: When entering a freeway from an on-ramp try to increase your speed to match that of the freeway traffic. Remember, you must yield the right of way to the traffic already on the freeway.
Freeway Driving: .....To be courteous to vehicles entering the freeway, you should change to the left (or center) lane, if you can do safely without slowing the traffic flow.
Following Too Closely (C.R.S. 42-4-1008(1)) "The driver of a motor vehicle shall not follow another vehicle more closely than is reasonable and prudent, having due regard for the speed of such vehicles and the traffic upon and the condition of the highway"
Yes and when you are 35+ feet and traffic is following as if it was a NASCAR drafting exercise.... someone needs to accommodate the merging vehicle.
In the OPs case I speculate the five cars behind the RV expected to pass so as not to be behind the large vehicle.
Ever put on your blinker and suddenly a few cars need to pass on that side? Happens all the time to me.
