Hi. One point you haven't mentioned is how do you expect to use the unit? Are you going to use it periodically and only locally? Do you expect to travel around the country? Will you full-time? The answer to these questions may necessarily tell you what kind of chassis you require and how much OCCC may be available for your needs. Further, if you use any of the plumbing within the coach, you will need to winterize the unit, unless you spend the winter down south in warmer climes. Otherwise, the factors that you listed can be had in many brands of smaller Class Cs (24 feet). Good luck with your search.
