We have a 23 foot Class C Coach House and it rides and handles very well; prior to it we owned a 19 foot Pleasure Way on a Dodge chassis. It was a fine unit and being a little shorter was easy to park; it also handled well. Reason we bought the Coach House was to have better beds, a good bathroom and shower, and more space to haul all the stuff we have. A longer Class C would have reduced cargo capacity compared to our shorter one. From what I've learned, there really isn't a Class B+, that's just a marketing term and generally not recognized by the industry standards which are based on how the motorhome is constructed, not some advertising idea. Generally speaking I think you will find that the shorter Class C's will ride and handle a little better than a Class B; the longer Class C's ride OK but are more limited on ease of handling and parking due to their length.
