I'm curious how many people would be interested in a light, small, and inexpensive two car open deck trailer.
It would cost around $8700, weigh 8000# loaded with two cars, 4 sets of tires, and around 600 pounds of tools and parts in locked storage.
It would have an angled deck and long ramps so loading would be easy. The load deck would only be 4" wider than a Miata so you could see around it in the mirrors of a typical SUV or Van. All that would stick out sideways past the tow vehicle would be the fenders. At 8000# you could tow it with a newer 1/2 ton truck, but a 3/4 would be better.
For the cost of a better open deck trailer you get a co-driver in the tow vehicle, twice the gas milage towing, one less tow vehicle to buy and insure, one less tow vehicle and trailer to store.
It won't have the drag, weight and wind gust sensitivity of an enclosed trailer big enough to do the same job. You won't need a 5th wheel and 1 ton truck. Tieing down the cars is easy because you can get to them.

Narrow width is a problem. Buying narrow axles is more costly. A narrow trailers' resale market would be limited because you couldn't get a full size car on it. Wind drag would be minimal between widths.

I see your point on narrow width and resale value, but resale value on this would be to another racer carrying two small cars, my idea is that a slightly more expensive trailer is justified by the savings of not investing in a second trailer and tow vehicle, plus gas, insurance, storage and maintenance for the second trailer and tow vehicle.
The customer I picture for one of these is a racer with a crew member who'd like to get into racing and can afford it,but doesn't have the space at the apartment or condo for the support vehicle and trailer. One trailer upgrade like this with another racer and they are both at the track
The narrow width makes it easy to see around when towing, easier to park in places. If it wasn't limited to small cars it would have to be a higher capacity trailer. There are other multicar trailers out there, some might even be cheaper, but they are most likely heavier, wider, don't have enclosed storage capacity, have loading issues getting on and off, and may need a bigger tow vehicle.

There's a guy here in Cen. Fl. Region that runs exactly what you're talking about for he and his wife's SM's. It has hydraulics that lift the top ramp up in place. I'll see if I can get him to post some pics of it.
I'm considering building 3 more units, that's why I'm trying to see how interested people on the forum are in this concept. I'm also trying to sell the prototype pretty cheap to someone who could use it over the winter.
The numbers on the website are a little off, this trailer weighs 3080# empty, next one will be around 2700#. Two Miatas on this trailer will hit 7300# leaving you 900# for tires and gear to hit a tongue weight of 1200#.
Just measured one of my Miata wheels, its 32# shaved low. 4 complete sets would be 512#, call it 540 with more weight thrown in for the treaded rain tires. That leaves you with 360 pounds of tools and spares on the prototype trailer (that is why its cheap, you'll have to put some stuff in the tow vehicle). The newer trailers will be at least 300# lighter so that figure will go up to over 600# of gear in the enclosed storage.
That is why this is specifically a light racecar trailer and aimed specifically at SM right now, axles jump in size, weight and cost at 3500#. The goal here is the most towing/storage for the least amount of money, size and tow vehicle capacity. A simple trailer with a pair of 3500# axles limits us to 7000# on the axles and weight distribution kits are good to 1200# tongue weight. Maybe 3 axles are needed, but then you are paying an extra $600 plus maintenance for an axle you may not need if you don't need more than 600# in the storage area.
If and when we decide to step up to carrying two A-sedans or Corvette size cars, the trailer gets wider/longer and a pair of 5000# axles or a third 3500# axle. It also gets more expensive and heavier.

I've got a 32' deck 3 axle tag trailer I bought several years ago for $4,000. These days eBay has a plethora of 28-36' 2 and 3 axle trailers for under $5k with 7k axles, LEDs, etc., etc. There is a market for such a size trailer, but I'm not sure at that price.
FWIW when I was shopping for mine 5-6 years ago most new 28'+ trailers were in the 8-10k range.

I built a 2 Miata trailer last year here at the school. I use it every week, the deck is 25 feet long and i think 70" wide total with tongue is around 40’. It weighs 1600lbs alone. With two cars around 6200, I pull it with a 05- F150. Pulls like my single car trailer at 70mph. I bought a trailer kit from a place in Texas for $900, which included everything except the frame. I picked up a set of trailer plans for a 20” on line for $30 and added to it. Total cost with LED lighting was $1600. DMV fees here in Cali was $55.

All valid points, there are several groups of trailer buyers and a large group might be people that buy the cheapest trailer and put the extra money in the car or going somewhere. Some guys are really handy and like building custom things for problems like this, that is where Shop Teacher and I started. But I think there are also a lot of people who would go the middle way and don't have the time/skill to build one and would pay a little more for a light simple trailer that works very well for the application. I see new aluminum single car trailers advertised for $4800, and people are buying plenty of these, and that's without any storage on the trailer.
Chris's three axle tag was cheaper to buy, but its wide and heavy. Most likely 82 inches wide at the deck instead of 70" and probably sturdy enough to carry two F-150s. A trailer with 3 7000# axles carrying two 2150# cars is pretty stiffly sprung, but the cars probably don't care.
Shop Teacher, you probably ought to sketch up some plans and sell them for beer money. Have you had many people make similar ones? Is it 25' with a 15' tongue, total of 40'?? Weight sounds very light, my goal is to get down to 2350# for the Miata version, but that is with tire racks and all the locked storage.
What both trailers probably don't have (I could be wrong) is the locked storage. This trailer has 6 locking doors and 95 cubic feet of storage. For reference a Tahoe has 108 cubic feet, floor to ceiling with the back seats down. The trailer does it with more doors and floor footage so most stuff is easier to get to. You also don't have to empty this stuff out of the tow vehicle after the race because its locked away in the trailer.
This is still about seeing how many people are interested in the idea, not looking so promising at the moment. The prototype is currently advertised at $5400 with the weight distribution hitch included.

The Swede's trailer is about the coolest thing I've ever seen. He tows it behind his RV or truck. The thing even holds a golf cart sideways at the rear. He's one hell of a fabricator and a pretty good driver thats for sure.
