The letters and numbers on a trailer often mean nothing. Yes most have letters that are somewhat desriptive, but others not so much. Mine is a 260TRS. Doesn't really mean anything. Could say the TRS means terrain rear slide, but terrains without rear slides have the same TRS branding.
The numbers are also misleading. My camper is a 260TRS and is about 29 total length. My brothers trailer is a Fun Finder 267RES and is 34 feet long.
Check out every trailer. Go to many dealers, and find an RV show. Our trailer wasn't AT ALL what we were looking for.... until we went in it and fell in love. You'd be surprised what you like. Take your time, have fun with it. Take everything the dealer says with a grain of salt, but don't assume they're just lying. My dealer was very honest, and helpful. Not once did they make up a statistic or fact like some do.
