I look at AllStays for road height warnings.
However, I must ask. Is 13'6" at mfr spec for your trailer, or an actual measurement?
The manufacturer height is what it is supposed to be if sitting on level ground with the floor level.
The tow truck hitch height can change the total height of a 5th wheel a bit. If it is not an actual measurement of the rig while hitched to your pickup/ tow truck, I urge you to measure yourself.
Does your rig 'tilt up' when viewed from the side while hooked to the truck, or down?
Also trailer with a long 'level' roof can be subject to pitching if the road surface changes under the tow vehicle. Which can cause the back of the trailer to rise a few inches in some situations.
