How tall is my rig

I set a 10 foot 2x4 on top of my tallest point (AC Unit) with a level on it to ensure it was level. I had my son-in-law measure from the bottom of the 2x4 to the ground, 12' 6".

Don't know.. When we bought ours, it had to go into dealers shop for a few minor things. I asked them to measure it and give me a good number. When we went to get it, there was a new sticker with permanent black numbers , and the word Height stuck on the speedometer where it couldn't be missed. Using that, we haven't had any problems.

dapperdan has the best response to the question with a perfect picture.
never rely on specs that come with 5er. too many variables with tow vehicle etc.
imho.

How tall is my rig? = the height from the ground to the tallest point measured in inches.

A have a tool called a Compulevel that will give me a digital readout to within 1/8". Even though it would be easy to do I have never measured the height of my trailer. I just assume it is 13'-6" and react accordingly.

I screwed a phenolic label with US and metric to the dash below speedomter

And just in case you should ever go to Canada; convert it to Meters and write that down too.

13'-6" is maximum allowed build height per federal law. Both commercial and non commercial vehicles in U.S. As others have said you must measure your own for individual height.

It is NOT a question of know the maximum allowed by law...it is a question of knowing YOUR maximum...

Point being it will not be higher than 13'-6". As the sign in your picture indicates 8' why would anyone take a possible up to 13'-6" and even try. Highways with clearances less than 15' are supposed to be posted as to height.

Couldn't you find an example without the plumbers crack?

The brochure lists the height at 12'8" with A/C.
