StarCraft Autumn Ridge to Launch Please explain.

That new Launch 26BHS looks to be based off of the parent company's, Jayco, Jay Flight 28BHS but with some features differing the biggest being a lower ceiling height. Your 278BH was based off of Jayco's Jay FLight 26BH.

Just another example of why the industrial standard for Travel Trailer length is bumper to hitch as model numbers do not represent the box size in many cases.

My guess is the autumn ridge was 1 foot 4 inches shorter if that is what the book says.

A friend of mine insists that his trailer is 26 feet because 26 is in the model number so when he looks for a site he always tells the campground 26 feet. His trailer is over 30 feet and half the time he is giving site that is small.

The model (like 26 BH) on TTs is the lenght of the box and floorplan (26 BH is a 26' box with a bunk house). The overall lenght is from tip of tongue to end of bumper. The tongue is usually 4'to 5' long, and from the back of the box to the outer end of the bumper is usually 6" to 1'. They usually do not add the spare tire (for some reason). So your 26 BH will officially measure 30' to 31' in total lenght.

As far as cover, well! Maybe your new trailer has a bit longer front nose, or maybe rear tail piece than your old trailer. Maybe your new trailer is a bit wider. Maybe your old trailer wasnt as long as your new one. Not trying to belittle you at all, Im just saying "looks can be deceiving" and you even mentioned that you never measured your old TT.

Hope you like the Launch. We are starting to get our first Autumn Ridge units to sell. They seem nice and sell good so far.

I am guessing you are talking about the length from hitch to bumper when you say overall length. Some trailers have a longer hitch length or bumper length or no bumper at all. When it comes to a cover you want the length of the box I think.
