How long is long?

all of your questions lack certain variables...how big of a sleeper are u talking about? the most common for company trucks is right around 70 inches (like the Century I drive). I don't know exactly how long my truck/trailer combo is, but I know it's within the legal length of all the 48 states and Canada. the only difference that varies is the axle distance (aka bridge law) which changes in every state.

 

As I originally stated, I honestly don't know how long my combo is. All I know is that I do not drive on a roadway in any state that is not highlighted in my Motor Carriers Road Atlas as a designate truck route unless I personally know the road (i.e. certain county roads in IL that aren't highlighted in the atlas but are STAA routes during summer months, mostly because of farming.)

Get yourself a Rand McNally Motor Carriers Road Atlas and follow it's suggestions, unless you are 100% certain of the law in that state.

Also, parts of US 101 in CA are not highlighted on that map. For example, if I were to leave Salinas, CA heading towards any northern point such as Oregon, WA, or northern CA, it would be less miles to run 101 all the way to I-280 (which becomes I-680), up to I-80, to the 505 to I-5. Instead, I have to take 101 to CA 156 west to CA 1 north, to CA 17 north to I-880 to CA 262 east to I 680.

I may be talking in circles here, since I don't know the exact length of my truck...but I believe it to be right around 65'
