JMO but first question to ask yourselves is how it will be used. Weekend warrior? Annual multi week trip? Retiree multi month/almost fulltime travel.
Are you a must have FHU type camper or prefer SPs, COE, county, BLM, events only having dry camping people? If you want to do the SPs etc. the first priority will be tankage. Anything less than 60gal does not last long at all. Next is galley size (lots of counter space), big fridge, plenty of pantry space. If doing SPs etc.size matters. Anything over say 35' & finding sites in those SPs etc. will be challenging. Some states are better/worse than others.
It is always nice to be able to be adaptable. The gingerbread that builders catch your eye with is way down the priority list. Do the research. Narrow the possible models down to just a few. Buy the right one the first time. Flipping after a year or so is expensive.
