Body Width Quirk I Need Possible Suggestions On

Question

Hi,
I hope I can explain this clearly so someone can help me.  I'm very familiar with the footer and page controls in Muse.  I've made a quick and dirty mock-up of a site:
http://hissign.com/newdevelopment/footertest
The above mock-up is just something I threw together to show how if you use the body width of Muse and pull on those header and footer controls, you'll have a seamless fluid site that grows accordingly.
So I'm now working on re-creating a website for a client in Muse.  The idea is to make all future changes to it in-house rather than go to the web design company and ask for changes and being charged an arm and a leg.  Muse will obviously allow this to happen for the client, who is excited about this capability.  I suggested a major re-design (I don't like the orange color scheme that's currently there) but got shot down.  Maybe that will take place down the road.
Anyway, so far my re-design is going well as it looks just about as close as I can make it to the original.  But there's a quirk in the design.  Below is the link to my re-design.  If you want to see the actual site for comparison and developed by the client's design company, just delete everything in front of the root of the URL:

Here is my quirk.  Notice in both sites (mine and the original) there's that orange body where the white text goes over it.  In order for me to make my version look precisely like the original, I had to draw an orange rectangle so it matches up with the top of the header.  The header contains the logo, that burgundy bar at the top, and there's also the top portion of the orange "body" background box.  I then drew the second orange box and joined it with the header graphic's top portion of the orange box.
The reason why I'm doing it this way is because in order to make my version look like the original - and because that orange background in the original is inside of the header, I cannot take advantage of the body width in Muse - to just make the width the orange color and let it cascade down as the page grows vertically.
So on master pages I keep having to make different masters and stretching the orange box vertically either shorter or longer, depending on the content on the page.  It seems to be working but it's getting to be a pain in the @@@ because you can imagine how I may have to keep making different masters of various vertical lenghs to fit the content for that page.
So I'm reaching out to the community to just see if there's an easier way to do this - or perhaps a trick that I'm unaware of to make this happen.
Again, I know this sounds like an odd and quirky thing to do.  In a perfect world, and if I was designing from scratch, I'd definitely use the Muse body width like it should be used (and like I did when I threw together the quick and dirty mock up at the first link above).  But for this one the only solution I've been able to come up with is the one described above.

OK here's some additional information.  First here is a snapshot of the fake site I made (the link to it is in my first post) to demonstrate that as you keep adding content in it (like the long text boxes), the white BG continues to just spread down further:
In the site I'm making for the client, look at the image below.  See how the header is joined to a rectangle orange box that becomes the "body" where all content appears over it?  (I've split it in the image below so you can see what I mean)...
I have to do it this way in order for the Muse version of the site to look like the original design.  If I simply fill the browser option in Muse with Orange, this is the result:
So that's why I have to draw these orange rectangles to match up with header, but then this solution is causing me issues with the vertical length of the site.  For example, on Master 1 I made the orange rectangle go all the way down to 1440 pixels.  One the home page it works fine.  Here is that page:
http://hissign.com/newdevelopment/index.html
But because some of the other pages may have much more content on them, using Master 1 will not work because Master 1's orange box cuts off at 1440.  Here is a page with Master 1 on it that has a lot more content on it, stretching it down further.  As you'll see, because the content is much longer, this Master does not work because the orange box cuts off:
http://hissign.com/newdevelopment/request-interpreter.html
So what I had to do is create a 2nd master page and stretch the orange box much longer so it is behind the content.
What I'm just trying to find out is if there is some other (i.e., easier) way to do this than how I'm doing it.
