Definitely a regional difference, though depending on where you might go with the camper, you will probably find you want a/c available as well. (Remember, everyone, "below zero" in Canada does not mean "below zero" in the U.S. ) Still pretty chilly for camping, though. :)
One thing we love about having a full-height trailer rather than a popup is just what you mentioned: pulling off the road (for us, it's usually in a rest area) and being able to access fridge, sink, etc. to make lunch, eat inside if the weather is bad or there are no picnic tables available, use the bathroom, etc. Not possible with a PUP; when we had ours, we kept most things in the tow vehicle anyway (an SUV in the day) and would just make sandwiches from our food boxes & cooler - but no place to sit inside except in the car. Then there was all that loading & unloading every time we set up or broke camp...It just got old - but it did take 17 years to get old. (We were younger then.)
