Verifying Height?

While the boards and ladders are good for exact measurements.
If I knew the specs on the RV was 13'9", I would not go under a 14' underpass. Maybe 14'6". Having that said. Rather than climb on the roof of your RV, Just use a stiff stand out tape and measure from your tallest part to the ground. Look in your manuals at the A/C unit that came with your RV and it should have dimensions I believe and add that height and round up to the nearest foot, plus 6 inches and you should be safe if you follow the posted heights. I believe the posted heights on highway overpasses are given with a 6" allowance

Yep nothing beats a tape measure a level and straight edge!!

Measure while hooked up.

I use a ruler, and do it a couple of times, and for fuel, the places that say desel will be good most of the time, now it's all happy-camping

The height should be checked on all RV no matter which type they are. After leaving the factory many things can change and make it higher. There is another person on this forum that puts his height and length in his signature so it is always available for him to see. JMO

I also used a straight 2x4, taped a level to it, and measured the distance to the ground at several high points. I used a label maker to record the height in both feet and meters and mounted it on the windshield.

I also used the 2x4 out from my AC unit. I put a level on the 2x4. To make it easier, I just measured to the top of the ladder while up there. Then measurd the rest of the way down to the ground after I was off the ladder. I then wrote that height down on paper and put it on my visor.

Yup. One of the first things I did to both of the fifth wheels I have owned was check the distance from the ground to the highest point, which was the top of the air conditioner shroud. What is interesting is both my fivers were right at 12'6".

No doubt at all what my hieght is anymore :)

What they said ^^^^^^^^
Ladder and a tape measure is pretty much the only way... IF towing that should be a number plastered in your memory at all times..!! Joe
