Any trailer is limited to a top speed of 55mph in California, not just RVers pulling a trailer.
CHP is not looking for RV'ers doing 60 or 62, they are looking for any driver going 15mph or faster over the speed limit. The reason is the graduated speeding fines in California. If your speed limit is 55, then don't do 70 or your fine doubled. For every 50 RVers doing 65 in a 5 minute period, there is going to be one doing 70 - that is who they are going to get and it is worth their time and the state of California time to wait a few minutes for the one idiot.
A person with a Class A license might want to stay closer to 55mph, don't want to lose that license.
If you are not pulling a trailer and your speed limit is 65mph, don't go 80 or over. Might want to keep it down a few notches below 80.
Never be the fastest driver on the road, make sure you are being passed every once and awhile.
No matter what speed you are going, if the CHP officer thinks you are driving dangerously, you will be ticketed.
