A couple of considerations:
Are you comfortable with backing a trailer? Of course for most people with practice they get better at it, but others, not so much. I'm OK with it but I'd much rather back a single vehicle. Fifth wheels are easier to back and a small fifth wheel(is there such a thing?) is what I would shoot for if I were changing to a towed RV.
If you get a trailer that has more room you need to consider how big that will be and size your tow vehicle accordingly. I see some rigs on the road that make me want to give them a wide berth. Not that you would make that mistake, just that size of the tow vehicle is important.
