Towing regulations

Just don’t toss your empty Budweiser cans out the window and you’ll be fine.

At 55’, it would stop many motorhomes towing a car. I’m under that with my truck camper and enclosed trailer behind it, but not by much.

When I tow double I'm over length and have never worried about it. I'm betting that the officer who stops me will be more concerned about a combination being unsafe than he ever would be about the letter of the law. So far I haven't been measured.

I'm right at 75' with the trailer no problems since I started 10/16, currently sitting at property I own on Lake Tahoe getting ready to head down to Baja Mexico.

i can not say for every state but yes 65 feet is max for one trailer/tow combo. but commercial double tow in ca is 75 feet. rv?
just never be even 1/4, one quarter inch over that.
some states restrict wheel base length or king pin to trunion.
max fed dot legal length is 58 flat or box van.--not same as wheel base length--.
longer requires a moving permit.
but unless your are crazy and want to push it, one should never get that long with a rv and a trailer behind.

According to RVIA the shortest maximum truck/camper combo is 55 feet for Maryland and the District of Columbia, all other states are at least 60-82 feet for the combo.

It's always best to read the actual published law when understanding how it may or may not impact you.

Maryland's specific passage

(1) Subject to paragraph (2) of this subsection, a combination of noncommercial vehicles consisting of a power unit and a travel trailer may not exceed 65 feet in length.

(2) The combination of vehicles exceeding 55 feet but authorized under this subsection may only be operated on:

(i) Any part of the interstate system or other State system highways that are designated by the Secretary in conjunction with the U.S. Department of Transportation; or

(ii) A highway that is the shortest practical route between a designated highway and:

1. A point of origin or destination on a particular day; or

2. For a distance not to exceed 1 mile, facilities for food, fuel, repairs, or rest.

Notice the exceptions for Interstates and primaries. They were built and maintained with federal money. With this and the full faith and credit clause in the Constitution, on the main roads it is pretty much the same everywhere, except for doubles, which kinda makes sense on the old interstates with the 25 mph on/off ramps

I believe that in CA, over forty foot are prohibited. There is a name for them like red flag or the like. Ask any CHP officer or look it up on line.
