trailer feedback

Hello All!!!!
For you trailer users, I am getting ready to purchase an enclosed trailer and want some feedback from owners. 24 foot trailers seem to be the norm for hauling most cars. I currently have "A" bodies but will someday end up with my Road Runner. A racer friend had a 24 but said he wished he got a 28 foot. The 24's are quite a bit less in price and I just don't see the extra expense for a 28 foot, for 4 feet of space. Not to mention the extra towing hassle??? I plan to travel to shows, maybe race a little for fun, so other than a golf cart or scooter and a few tools, I don't need much room for stuff.
Any suggestions, comments, etc., is much appreciated...
Hope everyone enjoyed their Thanksgiving!!!
