Smallest Enclosed Auto trailer that will accommodate a Cobra?

[DonC]

Over the past 9 years I've towed my ERA in a 14' Serpent Express behind a 2004 Ford Ranger with a 4.0L V6 (207 HP) for somewhere in the 30 to 40 thousand mile range.
The package with the car loaded is about 4400 lbs and I have yet to have a problem with the handling or stopping (electric brakes on both axles). When I tow from Oregon over to Colorado or down to California I could use and extra 50 HP climbing up into the Siskius the Blues or into southern Wyoming but, who couldn't. On nothing more severe than rolling terrain I can set the cruise control at 75 and stay there all day long.
Couldn't be more please with both the trailer and the truck (I refer to it as the Energizer Bunny of pickups).
When I initially got the trailer was careful about positioning the car to insure the tongue weight was where it was supposed to be and always check the tire pressure on the truck and trailer daily when towing. Installed a piece of 2X4 on the floor of the trailer to insure the car is always where it needs to be when loaded.
