Travel trailer carports
Travel trailers are the most forgiving RV to cover — and the rig whose owners most often order a structure that is a few feet too short, because the tongue does not count as "length" on the spec sheet.
Height is set by the air conditioner, not the roofline
As a rough illustration rather than a class rule, many travel trailers sit somewhere around 10 to 11 feet at the roofline, with a rooftop air conditioner adding perhaps another foot on top of that — but individual trailers vary, so treat those as examples and measure your own rather than relying on a category figure. The number in the brochure is frequently the roofline figure, which is why a structure ordered directly from a spec sheet can be exactly one air conditioner too short.
The fix is not to guess which figure you have. Ask the manufacturer whether the published height is measured to the roof surface or to the top of installed equipment — those are different numbers and both are published by different makers. If you cannot get a straight answer, measure it.
The tongue is the number people forget
Travel trailer model numbers and advertised lengths usually describe the box, not the coupler. The A-frame tongue projects forward of the front wall and has to fit inside the structure along with everything else, unless you are content to leave it sticking out into the weather.
If you plan to keep the trailer hitched, or to back the tow vehicle in behind it, that length stacks too. Deciding this before you order is considerably cheaper than deciding it afterwards.
Width is usually the easy dimension
A body width in the region of eight feet is common on travel trailers, but that is an illustrative figure rather than a universal one, so measure your own. The width question is in any case rarely about the trailer — it is about how much room you want beside it. Enough to walk past comfortably is one answer; enough to open the door, deploy the steps, and stand at the entry without turning sideways is a different and larger answer.
The mistake to avoid
Measure these before you shop
Every figure below is something you can establish with a tape measure and twenty minutes. None of it can be safely inferred from a model number.
- 01Ground to the highest point on the roof, including the air conditioner
- 02Coupler to rear bumper, not the advertised box length
- 03Rear ladder projection, if fitted
- 04Widest body point, ignoring mirrors and the awning
- 05Whether the tow vehicle will be stored under the same roof
Nominal size is not usable clearance
Whatever figures you arrive at, remember what they describe. The numbers above are the space your vehicle needs — the usable opening you must be able to drive into. Carports are advertised at nominal frame dimensions measured to the outside of the structure, and the legs, base rails, and corner braces all intrude on that opening.
This means the structure you order should be nominally larger than the clearance you calculated. How much larger depends on the specific frame, which is why the last step before ordering is always to confirm the clear opening against the manufacturer drawings rather than the listing headline.
What this page does not tell you
We do not state whether your build requires a permit, what wind or snow rating your structure needs, or whether a particular product is engineered for your site. Those are jurisdiction-specific and product-specific questions, and answering them generically would be worse than not answering them at all.
