As Danny posted, "Keystone used to...." but their marketing department is currently taking a different approach to how the portray their RV lines.
The information is still available, you just have to do some "sleuthing" to find it. On the Keystone website, if you click on "showroom" a new page will open with all of the brands listed alphabetically. Under each brand are three categories: Starting MSRP, Starting Length and Starting Weight.
You can essentially use the MSRP and length to determine the "price per foot" of each brand and each model. You can't use "only the MSRP" because a trailer line starting at 16,000 and a trailer line starting at 23,000 may not reflect the cheapest built (yes, I used "cheapest" to describe it purposely) trailer may not be the 16,000 one if that line starts at 16' and the 23,000 line starts at 30'. Calculating the two, the "cheapest" trailer would be the 23,000 line at 766 per foot vs the 16,000 line at 1,000 per foot.....
Put on your "Sherlock spectacles" and do your homework.....
