I'm not a full timer or retired, but I do know it's pretty much 50/50 what a person decides to use for full timing.
Yes, motor homes are nice. But you still have to climb 3-5 steps to get inside the door. If you have a toad, you still have to go through the exercise to unhitch the toad, handle the tow bar, and work with that brake controller system.
In a trailer (TT or 5er), you still have 3-5 steps to get inside the camper, but with power jacks, back-up camera's in tow vehicles, much-much-much better designed weight distribution systems that 30 years ago, auto leveling on some models, slides, and all the amenities, there's really not much difference between towing a trailer with a truck, or towing a car with a motor home. Both take effort, regardless of age or retirement status.
So, really, it's just 50/50. Basically I think it REALLY comes down to what each person can afford, and how they determine they will use their rig.
Another reason for a MH over a TT is the availability of all that basement space, especially if one is full timing. On the other hand, 5er's provide a lot of basement space too.
So, in the end, I still think it's just a personal preference, and how each person wants to use their equipment.
