Welcome to the Forum. Can't help you too much with what options to order - our Montana was "previously enjoyed" and appears to have most of the options/upgrades available at the time (2000). In our short experience with our unit, we've found we really like the Fantastic Vents, slide toppers and 10 gal water heater. The more we become familiar with our unit, we'll learn what's what. Just over a month and we'll be headed south on our first trip of the season!!
