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

We measured the height of the MH to include the ac unit. Everyone measured twice to be sure the door opening would be tall enough.

Except the general contractor that built the barn didn't tell anyone there was going to be a slight rise to the concrete leading to the entrance.

First tornado warning after the building was built I ran for my MH thinking I was sooo glad to have a garage to put the MH in. Got to the door and something made me get out to just make sure she'd clear it.

Well, the slight incline of the concrete pad leading to the building put that MH at just enough angle that it WOULD NOT go in. Measure from floor to top of door plenty of room, but put that MH on ever so slight of an incline and nada, zip room to pull her in.

So just saying make sure you include measurement to accommodate the entrance.

My contractor didn't. And now I was the proud owner of a very nice building meant to put my MH in which she never saw the inside of. 😞

So unless you are running flat straight in with your MH, get your calculator/abacus out and figure just what size door opening you really need!!

What size door is it ??? And how tall is the motorhome

[luberhill]

Well I’m at 14ft if I had the door open all the way, very slight incline going in,,, are the class c lower than an a

By law. no vehicle may be taller than 13'6" without special permits and routing. Nor more than 8'6" wide with the exception of farm equipment on farming roads.

and with the farm exception only RV"s (May be just motor homes) and Flat Bed Tow Trucks are allowed at 8'6" others are limited to 8'zero

Federal law, cannot be over 13'6", so you are good to go.

In Montana, the maximum height is 14 feet (MCA 61-10-103).

If it's too close and you are concerned....Drop the air and back in. Lower the ride height and be happy.

Usually seems the satilite dome is the highest point if equipped with one.

With the AC units, I'm right at 13'1". You shouldn't have a problem putting away any size coach....Dennis

A lot depends upon the approach to the door. Flat and level, no problem.

up Hill ? the rear of your coach may be to high. Same thing in reverse if the approach is down hill.

No street legal vehicle can be over 13'6" tall.

Bingo: A hill on the approach can make a big difference.

ours is 12'6. I'd be looking for one that is LESS than 13'6.

Agree I am only 12'9" - and most diesel pushers are higher

[chuckftboy]

You will have no problem with most class A's I've never seen one over 13'6"
