Pop up camper vs hard sided camper

My wife told me "to surrender the fantasy" I still think I am 25 but my wife and my knees remind me that we are 72. So have started to investigate some 25-27 ft 5th wheels. I am guessing that a short 5th wheel set up would lean less when rounding a corner on mountainous roads than a HS TC, A or C, would that be true? Have more FW capacity than a pop up camper, more storage in general and easier to leave at the campsite than a HS TC. Also thinking you can store stuff in the truck bed like more water when dry camping. And lastly what drove me to look at the TC originally was using the truck as a second vehicle, but when I heard most on here eventually ended up with a DRW I figured I could tow a small 5th wheel with a SRW truck and maybe even the newer Ford 150. Everything is a compromise.
