We had a popup, specifically so we could go off-road. We now have a hard-side expandable, and it can still go off-road. But, no TT can go most of the places we go, due to trees being too close to the trail.
While not all popup owners take them off-road, I would venture that at least 25% of PUPs go 4-wheelin' frequently. That is one reason they will always be the choice for some.
Others enjoy the better fuel efficiency of towing a PUP, as you can easily get half-again the mileage as someone towing a TT, with its high front wall.
PUPs have their niche. For some, the price is not the only consideration. Functionality is a major part of the equation. Add amenities to the PUP, and they do get pricey. But, there is less difference in functionality of a PUP to a TT when you add the pricey amenities. I am willing to pay for comfort in an expandable. You may not be willing to pay for what I consider very important. No problem.
