I went through the same thing 15 years ago (wow I can't believe my trailer is 15 years old) and decided on a trailer for a few reasons.
Probably the biggest reason was perceived maintenance and breakdown recovery. I figured if I had an engine or transmission problem on the road I could go almost anywhere to have a Chevy Suburban repaired. Fortunately I never broke down on the road, but that was the reason.
Fast forward that 15 years with a divorce and kids in their teens and a MH is starting to be more desirable as you can just get in, turn the key and go. But in the end I can't remember ever camping and not getting in the Suburban to go somewhere so I'll probably stay with a trailer.
