Enclosed Trailer/Car Hauler feedback

[Demps]

There has been a lot of talk about folks buying trailers. I have an open Trailerworld aluminium 16' airdam trailer perfect for the ZR-1--except now I'm wanting an enclosed trailer for my non-drivers. I'm thinking of stepping up to an enclosed trailer. I will be towing with a 5.7L DOHC Tundra (381 hp, 401 lb-ft -->sound remotely familiar?) that is rated at 10,300lbs.

Please give some feedback for those (Chris) that have recently bought (or owned for a while) about:

1) what you would do differently?
2) does "size" matter--20-26ft?
3) axle rating?
4) front stowage options?
5) front taper (vee or angled roof)?
6) door placement/functionality?

thanks,
Ted
