The first thing to realize is the AAA list, as well as others I have found, is badly out of date. In general there has been a trend toward increasing length and width limits and also decreasing the threshold at which brakes are required. The Minnesota section, by way of example, is several years out of date.
The second thing to realize is, as others have posted, RVs are generally not expected to comply with laws and regulations adopted for the trucking industry.
In my experience there are a number of things to watch where you can indeed get stopped:
1) You must have lights that work properly
2) You must have current registration
3) There are many jurisdictions that disallow doubles and these rules are enforced
4) They will stop you for a violation of maximum length limits, which is really only a problem for some unusual older trailers e.g. the longer Spartans
5) You must have safety chains, and they will stop you if they are dragging and sending sparks flying
6) Routes in the mountains that have posted length width and height limits are enforced
