A 6' wide trailer, certainly one with a 6' height with interior wheel wells becomes a liability for manufacturers when the people who use them do not understand that they can not load them like one with exterior wheels. If they are loaded like a typical trailer, they could get awful tippy and they would also be a whole lot more susceptible for flipping in higher winds simply because they would be narrower. Sure, lots of flat utility trailers are built with narrower axles, but you do not see them loaded 6' high and 6' wide.
Manufacturers already set their axles back farther than those of us who like to convert them would like just to keep those who do not know how to load trailers a little bit safer. In other words, they make it harder for people to screw up.
This pushes builders into a 7' wide trailer if you want inside wheel wells. The only common build for these are vendor trailers and they cost quite a bit more to build and buy. they are not as common to find, but they are available. I think any one of the trailer builders will build you one, but hang on to your wallet when you hear the price. When you find a vendor trailer, note to that many of them also have a more centered axle (still slightly towards the rear) because they use the floor plans and water tank placements to properly load the trailer regarding tongue weight.
But back to the 6' wide... people do buy them over 7' wide so they can see around them. I didn't want a 7' wide behind my minivan (a 6' wide is enough of a challenge for it), but with a7' wide, the challenge of staying within the 2990lb weight limit becomes even more tricky, similar to the 6'x14' single axle trailers because of the added space.
If money was no object, a good replacement for the traditional and popular 6x12 would be a 6 1/2 foot wide inside trailer with semi recessed wheels similar to the 102" wide trailers. Then a whole lot more people could sleep across the trailer and get more useful floor plan options. They will never build them though... the 6' wides are a pretty quick build.
