John,
On January 20th you sent me an email with all these drawing and asked me to get them. I printed them all out and told you I would be
happy to do so and would take the measurements the next time I was at my workshop. You noted that you weren't in a hurry for them. I
have not been to my workshop since then due to issues I am dealing with at home.
Now you've published them which is going to cause redundant effort by people who participate in this forum!

Hey all,
I need some dims. Here is a bunch of drawings with the dims I need called out.

Hopefully, it all makes sense. Measurements can be in Inches, mm, or cubits, I can do the math. :d
Thank you all.

Hey Rob,
You are right, I did email pics to you for dims. And I greatly appreciate the offer of help. And posting this publicly, as such, I in no way meant to insult you. And it's not because you haven't had time to get me numbers (you, unlike myself, have a life).
While I am in no real hurry, I just thought a bunch of people working on it would be better than trying to have one person provide all the data.

Getting some, what would seem to be, redundant data is not a bad thing here. It will help ensure the data is right, by multiple points being close or the same.

John,
I am about to head down to my workshop and I'll get as many of the measurements I can for you today.
Being the anally retentive pedantic bastard that I am you can bet dollars to donuts that they'll be correct! ;-)
I discovered The Big Bang Theory while I was in the USA last year and I have gotten addicted to it. It is shown down here and I have
come to realize I'm a lot like Sheldon in some ways. I'm not as egocentric though. Well I believe I'm not anyway! ;-)

John and Rob,
A relatively easy way to do this would be to volunteer to take measurements
on a particular image. For instance, Rob, you could say I'll do the
passenger side of the 260 and have at it. That way, another dude who
actually owns a 23-footer, could say he'd get his wife to do the driver
side, etc. That way, those who've expressed an interest in this project
could put their hands, eyes, feet, and brain where their fingers were when
the jumped in with so much excitement.
Just sayin'

Once you have collected and collated the measurements, would you please post the data? I'm sure at some point someone else may want this data in the future.
Thanks!

That would be great Sheldon. Thanks. These I thought would be the hardest to get, as they are usually hidden, and never seen. Unless something bad has happened, or you have taken on a project that will destroy you (and maybe a coach or three). 
There are other structural members I would love to get dims on too. But there are not needed to design and build the model kit. They are for another project I would like to do: A complete detailed computer model of the coach. There are a couple of beams there I didn't do up yet. The big H-Beam at the belt-line, and the 2 (2+ a C-Channel??) at the side/roof transition. As well as the C-Channel that most of the roof's longitudinal beams are made of. As seen in this pic here.

Oh, absolutely. This data is not secret stuff or anything.
But once I have drawings and stuff done, I will share, and give credit where it is due, of course.

Oh Rob, I know about the anal thing.  I am the same way. Look at the trouble I am going through to make a model kit. I could just cut up a couple of HESS vans, and be done with it. 99% of the people looking at it will know what it is, and be happy with it. But *I* will only the see the glaring errors in the shape and proportions and details, and so on.  Can't have that. Nope.
And Byron, you have a good idea there: people grab a section, and go from there. I like that.

Crap, one more thing for this morning...
Anyone have a coach that (they can get to and) has the windshield out??
What I would REALLY like to get is the shape of both the top and bottom of the opening. This would provide me with tons of data on the window, of course, but of the body shape for the front. Actually, one could measure the window itself, and get almost the same data. That would work too.
If you have such a coach, and willing to help... Please get in touch with about how to measure this up.
There are three ways to do it:
1) Send me a windshield or a complete front clip (probably not feasible).
2) Trace the shape on paper stuck to a piece of plywood (to keep it stiff), and send that to me, or...
3) Provide data points per this diagram here.

John,
There were a number of changes/modifications throughout the six years of production. Some documented, some not, some known, some not so well. These comments are intended to make your choices hopefully simpler.
Comments:
- Choose the model years 1975-1978. The design had settled down, the early years had many changes.
- Choose the "standard" window layout for the base model. It had the largest build/was most popular.
- There were body structure changes for most years. Most would probably not bother your design, just don't be suprised, they are not all the same.
- If you choose a "model" be aware of its intended purpose, i.e., the 1/16 model was for CD studies (smooth, detail missing).
Hess model looks great, Barbie & HotWheels almost can't tell they represent GMC MHs.
- The GMC body dimension document was for internal structure location for upfitters without concern for exteriors.
- Sirums in FL have a number of stripped GMCs in their back lot. I do have a number of internal photos of these, not sure they would be of any use to you.

BTW, your picture didn't show up, at least for me. But I did find it, I think, after a little surfing.
As for the "Chineese guys"... I have NO idea what that is in reference too. Sorry.

Thanks Bill. But I am aware of these issues. That's why I am here, to try and document and/or clarify as many as possible. Ugh!

My understanding, and research so far, shows that the basic shape, once set before production, didn't change. Other than window placement and the like. As each model's interior would dictate the placement of the windows and the like. And with interior layout/equipment changes, exterior bits changed too: Vents, grills, access hatches...
| Quote: |
- Choose the "standard" window layout for the base model. It had the largest build/was most popular.
|
My plan, as of now, is to be able to put the kit together in a modular way, so almost ALL variations are possible. Subject to change, of course. And of course, everyone who has made mods to their coach, will have yet another version of the layout and window placement. Right now, I am working on the 3 basic models each for the 230 and 260. See this graphic here.

No surprise for me here. Internal changes affect the look of the exterior, of course, where windows and that are concerned. There could be 1 or 100 internal changes, but as you say, probably not bother my design.

As reference?? Never. I'm smarter than your average bear. So, as soon as I saw them, I knew they were wrong. Well, the 1/16 model is not wrong as such, but not fully detailed out. It would be useful to have one to grab contours off of. But, I ain't gots one. So... The Barbie version is, well, it's like, hmm.. Well, it is. Just that. The HESS van is interesting, as the most accurate, sorta. It's got all the features of the 260, crammed into the length of the 230. This changes the contour of the front the most, making it too upright. The windshield needs to lean back more.

Yeah, I know. Damnitalltohell. That's why I am here, trying to get more numbers to work with.

More reference material is always welcome. If you are willing to share, I would be very appreciative. Thank you.

My bad, Chineese as copy cat's, going so close in to the details made me wonder if we would see the chineese full size version of our GMC on the road soon
And not a bad wourd about the chinese people, I was in a relationship with a chinese girl not so long a go

John,
Going strictly by my '76 Birchaven, it seems GMC made the sub-skin
structure as common as possible, so that only the skin required
modification for variations.
Two examples:
1. I wanted to lengthen the right side window. The task was greatly
simplified when I found that the shorter window common to Birchavens was
framed with an added upright -- the basic frame for the longer window
common to 26' coaches was in place. Only cutting sheet metal was necessary
to create the needed opening.
2. Mine is the only 23' coach I've seen with an access door like that on
the left side of most 26' coaches. And mine came from a 26' coach -- I
added it at the left rear. But when I cut the opening through the skin for
that door it was to utilize framework that was in place before the skin was
applied at the factory. In fact, no only was the opening framed, the
aluminum tab for the door latch had been welded in place. Someone planned
ahead -- apparently just for me. :-)
