They are really a tent with built-in trailer. Initial setup (roof over your head) is pretty quick, but then everything else needs to be set up afterward, and packed up as well. The jayco stye is almost the opposite: the raising and lowering of the roof is the big item, the internal setup stays fixed. I think this is easier to live with with frequent moves from site to site (but each to their own.)
I got my Pajero hung up the other day and needed a tow by a friendly local farmer - the camper didn't touch ground at any time (but does have raised off-road chassis). an off-road Jayco will go anywhere you would want to take a towed trailer. The Jurgens type van has rear cutaway for clearance. Even the most basic box-trailer based design will cope with everything except prolonged corregations.
As for length - from past caravan experience 16ft of living space is the minimum for a family. If you are travelling every other day, I'd suggest an awning rather then a full annexe. And if you are on any sort of budget, I'd suggest you steer away from 4-bed off-road camper trailers- you could replace your tow vehicle for the price of the camper, while box-trailer and jayco-style campers can be had in excellent condition for around $5000.
