Take the time to make sure that you are happy with it. It will set the tone for your entire build. Do not under value it.
Yes, playing with radii and center locations and ellipsis can become maddening, but you must not "settle" until you are truly satisfied.
You really do appear to have gotten a true handle on Sketchup; use it to your advantage and seal the deal.
That said, what you have shown looks pretty damn good. It proves to me that you know what you are doing and can make whatever changes you need to to get that extra 5/ct to make yourself truly happy. My personal preference is not so concerned with covering the frame because I would rather crash steel on stone than wood, but that is a function of my intended use and vision, as much as yours is for you.
What I have learned is that this is a much more involved and longer process than we might have originally thought (... depends on your goals and threshold of quality, of course), so take your time and please yourself.
You have some good points. It's just that the built in tools where very limited for modeling a classic style profile. By default, there is circles, rectangles, and arcs. Arcs cannot be draw non-symmetrically. So I basically got that original shape looking fairly good somewhat by chance with a bit of frustration. Today, I tried updating the shape to go down to the bottom of the wood subframe and extent more forward, and was getting exasperated with the limited curve drawing tools after about half an hour of no progress. Getting too annoyed to continue that way, I started searching, and quickly discovered that Sketchup allows plug-ins. I got a curve plug-in, and shaped up a very nice looking curve with ease, using the Beizer curve tool.
This may be a little tricky to copy onto the actual foam, but it shouldn't be that hard. I should be able to use a grid to transfer the curve manually from computer to the foam.
Here's a much better model. The colors of the roof and walls are different for clarity, and not pink because the final color will definitely not be pink, and I didn't want an unpleasant (to me) color throwing off how I thought of the profile. Still not complete, but the usefulness of the model cannot be understated, as you have said. Getting even better at Sketchup, too.

(This is not my first model)

It's a given there will be changes before I commit, but I would venture to say this is fairly close to how the overall shape will look. I need to double check clearance for tight maneuvering, the TD may extend too far forward to be able to really crank the trailer over if I need to in a particular back-up scenario. I will model a version where the curve's profile goes down another couple inches to cover the HF frame to compare. I also want to model a tongue box, however, I'm planning to avoid one unless my trailer does not balance as desired, as I like the cleaner look of a TD without a tongue box. I'm thinking I can hide the deep cycle battery in the front curve of the TD if I need a little more tongue weight. I am also considering the smallest window shaker AC I can find, might be nice for those hot summer days it's hard to sleep in. Not sure if I want a permanent mount, removable, or convert the AC to a portable unit that connects with hoses. Still lots to consider.
GPW, does the polyurethane in "the mix" need to be exterior? Asking because the previous owners of my house left among the various paints/wood finishes, two gallons of interior oil based poly. I figure the mix is a lot nicer then the "black goo" to apply to the sub-frame for protection (especially easy using my compressor and a cheap HF spray gun!), and if it will work okay, it's free! Also other stuff like door, window, roof fan, and hatch framing needs the mix applied before painting, and I figure interior should be good there, just curious about interior with "the mix" to protect the sub-frame from road spray.

Just for fun, this was my first model in Sketchup. I was planning an aquarium stand to hold two 20 gallon long tanks.

Verses the real thing (CO2 tank not added yet):

Was really cool comparing the semi-final model to the semi-final product. The TD model to product is going to be much cooler.
