Is my barn door tall enough for a class a

[luberhill]

Ok my pole barn is 28 x 40 ft with 16 ft walls.. my one overhead door is 12 ft wide by 14 ft tall... now the door probably hangs down about 3” from the header so the opening is probably 13’6”
I can probably adjust it to open to the full 14ft
We may get a class C it an A.. probably 29 FYI long or less... what’s the height needed with the ac unit etc

[catkins]

Beware added height from AC units, over air antennas, roof vent covers, any satellite dish on the roof and any other additions the manufacturer puts on. Not sure what they measure when they say this is THE height.

Class Cs generally are a little less high but vary widely. That sloped driveway can be the cause of real life issues. Wish you luck in figuring it all out and being able to use that great looking shed!

Is that measurement to the top of the vehicle or all the way up to include ac?

It's the overall height of the vehicle and/or load. The laws don't care whether it's a cab or a crane boom or a tank or an air conditioner or a pile of logs at the top, just how tall the vehicle is. Similarly, railroad underpasses and wires and the like aren't really picky about whether it's the roof or something else that doesn't fit underneath; it causes trouble regardless.

The widths generally do permit a couple of inches of "free" width for ancillary doodads that attach to the vehicle like lights or door handles. They also typically do not apply to side rear view mirrors (or at least a reasonable amount of extra is allowed for mirrors).

Only option I see to use your barn door opening size is to have the drive redone and level 40 ft out from the door, or modify the door opening and door.
If I was going to build one I would want 20 ft ceiling and at least 14 ft door opening so I could caulk the roof or wash the rig, with drains in floor or course and 18 to 20 ft wide so I could open slides and room to move around the coach.

wa8yxm might check NC width laws, length laws, etc. For instance the 120in width and 90ft length laws that apply to towing boats and RVs----still 13-6 high

[Grey_Mountain]

If you are just a tad too high,invite ten of your fattest friends over to ride in with you. The extra weight maybe just enough to lower the coach to a workable height.

1/4” clearance ??? So if there is a stone under your tire it will hit

My door is 12' high. My Class "A" is 11'11 3/4". Wife watched me go in first time. if it goes in once it will go in again, just have to make sure door is totally up. That is why i bought my Fleetwood Storm. Specs said 12' high measured it 3 times at Lazydays in Fl, all good.

Hopefully this video will fix the magic number into your head.

We're at 12ft 10", like most DP A's, but they can vary some and should be in the specs., once you get things narrowed down.

[luberhill]

Well I don’t have an RV yet... but looking at 29 ft Winnebago,,, they list them at 11.5ft high to the tallest point,,, the opening now is 13’8” but again I can adjust the opener to get the full 14 ft but I don’t think I’ll need it

[bumpus4]

Please don't chance it. Measure from the top of the MH highest point. Include the top of the a/cond. Measure the door opening height.

It is hard to give any other advice without knowing the Make/Mod./Year and equipment on top of your MH.

If you have the S/N (or Vin) call the factory for height info, if you have the phone number. It should be in the owners manual.

Let us know the outcome. I am wanting to build a rv shed for my 2016 RV. It measures 13"6' at the highest point as measured by Escapees.
I am going for a 16" opening just to be on the safe side.
