Yes, continue investigating. It is reasonable to spend a few months if not a year reading everything you can get your hands on. As I posted above I, too, thought it a good idea for a single man and I still do. Here's why I thought it was good:
My grandparents and parents both had all-aluminum trailers (bigger, more heavy duty than an A/S) and I had grown up around it. Granted, this was for vacations and we rarely traveled in the winter. (WInters in Texas may not have the temps that are found up north, but they can defined by constant 20-30 mph winds which find every tiny leak in a trailer -- of which there are no small number).
I've worked on cars and houses plenty, and though I'm a long way from being expert at any of it, there is none of it that can be said to be unfamiliar; be it suspension dynamics, plumbing, electrical, rigging a conventional hitch, etc. I also spent time on the road as a professional.
Trailers share, with boats and airplances, the need for a knowledgeable owner. First step is manuals and books and familiarization, as it will be needed. Good RV techs are few and far between. So, if one is dependent on others to fix things, the full-time RV life coupled to full-time career has certain antagonisms. Where I live, losing an air-conditioner means I'm off to a motel for up to a week. A plumbing leak can be even more of a problem. Etcetera.
The reason I say "good for a single man" is that the women of my family or acquaintance are unlikely to put up with very many problems over the course of a year. Most people, I think, are not far from this problem of accepting mechanical/electrical/plumbing "inconveniences". There is always something.
Granted, a brand-new unit may not have problems of this sort, it may be quite awhile before they crop up due to age and use. An RV is built to be light, its components do not have the beef of those where weight is irrelevant. In a single year of full-timing one may accumulate more hours of trailer use than the average owner sees in ten years of vacationing.
Now, back to winter. Aluminum trailers are not the ones best suited for cold conditions. You should have a look at two brands:
New Horizons RV: Travel trailer
These are the two quality SOB (Some Other Brand) trailers I see most frequently cited by others as being of good construction AND capable of winter living. I have no experience with either, but I hope you'll have a look at the construction differences between A/S and this (plus that they are pigs to tow no matter how well built; not to mention danged heavy so a one-ton truck is likely).
I'd look for and solicit responses on rv.net and other forums to get first-hand info on winter RV living. RV's, in general, are three-season vehicles.
The problems of winter living (sub-40F) are not to be taken lightly. Propane systems, frozen plumbing potential, etc are issues you'll want to be familiar with.
You can "master" (sorta) the three-season stuff in about two weeks. Faster if you'll ask others for help. Towing is another creature.
Towing a trailer ain't rocket science but be aware that AT LEAST 90% of all rigs are incorrectly hitched, rigged, balanced or suspended. That's before they pull off the curb. Driving one takes more time and attention, and the skill level takes a while too. It's a fine challenge, and this particular forum does a better job of it than the others I have read.
Next are lists. There are several but all entail purchases that differ somewhat from owning a house. You'll need tools, but you won't have room or capacity for 300-lbs of them. You'll want spares, supplies and items which make RV'ng a lot easier. Etcetera. Look for pre-purchase check-lists and lists of what to pack along. Here and other boards. Hundreds of items to consider.
Finally, trailers, no matter the size, simply don't have a lot of storage room. Mine is big at 34-feet, but even alone I don't know where I'd keep a professional wardrobe of five suits and accessories, plus other clothing, shoes, coats what-have-you. I'd run out of room.
It can be done, but, please take your time, consider your options and continue investigating.
