No surprises in the links above...Like I said "except a teardrop shape."
The tail of all TT's are flat. The AirStream design is the only (albeit slight) exception. That is not good for aerodynamics, but they are all the same.
My comment was NOT about turbulence. I was talking about simple aerodynamics (wind drag) on the leading edge. A V-Nose will cut the front end wind drag compared to a flat or even slightly angled front cap.
I proved this in a real-life experience on an enclosed cargo trailer I built. Towing it, my small truck could not run freeway speeds with the AirCon without overheating. I added a V-Nose to it which allowed me to run without overheating.
The V-Nose also takes advantage of the otherwise lost space over the tongue.
The best, I would think would be the V-Nose and angled roof like:
Safe travels

When was the last time you saw a "V" nose airplane or space shuttle, ever see a tractor trailer with a v nose trailer.
In the grand scheme of things does this really matter who is right or wrong on this subject..if it does to you then your "right".
I am sorry I started it. I have better things to do,like being with my grand kids.
Travel safely

A model A Ford is much more aerodynamic backwards than forwards. That being said, I think the fuel mileage difference in two trailers of the same size and weight. will be negligible and not nearly as important as floorplan and amenities.

Well...here's a famous one, just turned 90' but the same effect on drag:
Safe travels to you and enjoy your Grandkids. We enjoy ours

Cliffy good luck, we ran into a really good used TT, we had already decided on a rear lounge floor plan, and this on was perfect for us !

Not to keep stirring a pot but having recent experience with flat vs V front, I will weigh in.
I think most here would agree that it is all about the headwind and grade. But near as I can tell, in level, low wind driving, 60-65 mph... mileage is about the same +/- 1 mpg... my two TTs are same length but the Super-V weighs in about a ton heavier.

Seems odd when you look at what is available in 5th wheels that we don't want.
I'd want a front bath-rear bedroom set up. Why can't I find one?
Just starting to look for a new or "newer" rig. 18' to 24' BOX.
I was told by one dealer to put a hitch socket on the back of a TT and then unhook from towing, go around the back with the truck and hook up to that ball and "push" the TT into the spot so the forward facing big windows would be looking at the lake. Hmmmmm!

Take a look at the Arctic Fox 32A. We ordered ours from the factory with some changes/upgrades, but the recliners look out the back window.

While I don't own a TT yet, I have been researching quite a bit. Trying to nail down what exactly we want in a TT. Seems like there are plenty of of makes/model that would work for you. The seasoned guys can correct me if I'm wrong but it seems like many manufactures use similar "wording" for their models. It seems as though many companies use the letters "RLS" or "RLS" for models that have a large living space in the rear with the bed/bath up front. Manufactures website all have the "floor plan" tabs to show what they offer.

I don't think there is a universal code for the model numbers/letters (for lack of better words). My opinion of "RLS" is Rear Living-room Slide - so, living room is in the back and the model has a slide. Not universal, but usually close. For my model - Jayco 32BHDS - 32ft long, Bunk House Dual Slides - I have a bunk house model with two slides.

Right, Nuny'. Not totally universal but would be a good starting point for the OP to weed out some of the models he/she doesn't want.

A teardrop leading edge is obviously best for mid-level wind speeds, but the V-Nose should look like this in a wind tunnel:

Most airplanes I've flown aren't being towed by pickup trucks!
If the aerodynamic front of the TT was the part that was actually "breaking" the wind instead of the pickup, I'd say you would be on to something, but what you actually end up with between the truck and trailer is turbulence, not so much Flat Plate Drag, so it doesn't matter a large amount whether it is streamlined or not except for the portion that is actually a greater height than your pickup. When we had a TT, we were towing with a pickup that had a topper on the back, one of those that got taller as it went back. If you want to see how the airflow is affecting your TT, tape a bunch of 1' long pieces of yarn all over the front of your TT, have someone else drive the truck, and check out which way the pieces of yarn are "flowing" or pointing in the airflow as you drive down the highway. Poor man's wind tunnel. Ideally, all the yarn on the outer edges will point away from the center front of TT, but in reality, a lot of them will be flying around all over the place . . . = Turbulence.

Turbulence = more wind resistance. More wind resistance = worse fuel economy . . . .
