I still need to figure out what they mean by 14 as well. I've got my install so I'm pretty happy with how it looks and fits.
While I don't necessarily disagree with you, I think some of your expectations may not be realistic BASED ON THE MARKET. There isn't much competition in the market, and every single one is custom so the customer base is quite limited.
I will say this, the cab I had for my
L39 was a little bit "better" in my opinion. It was made by these people:
Welcome to USA Tractor Cabs :: Vinyl and Acrylic Tractor Cabs
It had a better front windshield, it allowed use of the backhoe (not really important to me in winter), the door access was better, it was quicker to install, the side and rear panels rolled up nicely. It did have drawbacks. It went over the top of the machine so it was more susceptible to damage from low hanging branches, the sides didn't "slide".
I think what we got compares better with their $900 offer, for $1500 like they think what we got is worth you'd get a far superior product from usatractorcabs. For $500, what we got is a STEAL.
I think next time around I might attempt to build my own hard, but easily removable, cab.
