One thing that hasn't been talked about (for the OPs sake), but mentioned briefly by valhalla360 is POWER.
Yes there are HD trucks rated to tow this weight and any of the recent years gassers will pull it. A few better than others.
But a trailer this size is well into diesel territory for a comfortable pull with no fanfare, no loss of power on hills, etc.
Not to mention the virtues of an exhaust brake, which is a HUGE advantage/feature of all diesels that come with them and easily added to older ones, when it comes to towing houses.
