My 2 cents.
Mine is an entry level Carson 20 foot Racer model.
It came with a door and a ramp, over time I accessorized it.
Couple quick thoughts.
Windows are nice at the track but in public storage your trailer may be more vulnerable.
Check the trailer height if you want to put it next to your house under your roof eve.
Check the ramp and trailer frame have been engineered for weight of a car and not just desert toys.
Make sure it has electric brakes.
I'd rather have a V nose front, something with a little less drag.
A side awning adds comfort too.
A winch for loading with a remote control is a great help too.
Towing handling was improved greatly when I added this weight distributing hitch.
For the lower cars, club member Jim Copp makes these very cool ramps.
