We have had both. Previously we had a Lance, now we have an Outfitter.
A big plus on the tent type is mobility in the back country. Ours is just low enough to keep on going whereas a full height TC is going to be bushwacking a lot of limbs causing damage to the camper, or just not able to proceed.
On side hills we generally have an advantage of a lower center of gravity.
As far as setup, for us its not an issue, maybe 3 minutes at the most, if a full height TC has a slide well its about the same.
From my experience its just easier to unload a popup and it fits in our garage. Part of it may be the electric jacks.
Some people talk about boondocking being more difficult because the popup is showing, well most people just don't know and don't care. Its never been an issue anywhere, including downtown Washington D.C.
Oh, how about those bears. Our roof fully loaded is probably about 700 lbs, drop that on a bear that is dumb enough to climb up 7 feet, and try to get in through the vinyl and he is going to have a sore neck. A bear is more likely to come in through a lower open window or a door, and guess what, a hardside has the same openings.
Winter, we are comfortable down to about -20 degrees.
We like ours, The hardside campers have their supporters, and that is fine with me, to each their own.
We have owned ours for 7 years and 60,000 to 70,000 miles. We plan to keep it for the foreseeable future.
Good Luck!
