I am currently selling my hybrid as part of upgrading to a 29.5BHDS fifth wheel. While these may not apply to you, my reasons for moving on are:
1) Tired of climbing over the wife to get in/out of bed in the hybrid; my 2 girls have also grown out of sleeping in the same bunk
2) Near zero privacy when getting dressed
3) While set up / break down of camp with the hybrid isn't overly difficult, it does require 2 people to close up the bunks properly and can be a bit time more consuming compared to setting up a TT or 5'er. Carrying a 4' ladder became mandatory as well.
4) Closing up the bunk ends in the rain means opening it up when I get home to dry things out, no different than if I was in a tent.
5) Sound. No camper is soundproof of course, but let's say I'll never again camp at a Nascar event in a hybrid
6) Camping while hooked up to your truck. At least for our current hybrid, can't open the front bunk w/o detaching from the truck. Not too big a deal except for cross country / rest area stops where you just want to rest overnight. In those cases you'd be forced to set everything up. Contrast that to a TT or 5'er where you can stay hooked up (assuming you are more or less level of course).
6) Too bright in the morning. Hybrids let in a ton of light so if you want to sleep in late, that morning sun is going to be a challenge to fend off. PopUp Gizmos help a bit.
7) Condensation inside the canvas in the morning. Weather dependent, and more or less manageable with PopUp Gizmos, but those add to your set up and break down times.
