We have a trailer and are very happy with it. We don't full time, but we do go for 5-6'weeks at a time. Contrary to sometimes popular opinion, we didn't "settle" on a trailer because we didn't have the money for a Class A. We much prefer having a truck to do our other activities. We go canoeing, and the put Ins and take outs can be rough. Truck doesn't care. We can head up a snowy mountain road and don't worry about it. We can leave our living quarters hooked up and go to the grocery store. Yes, you can do these things with a Class A or C and a jeep or truck toad, but that's not what you have meaning extra expense. My 24' (box) trailer fits in those small sites in the FS campgrounds we prefer. Because it doesn't have extras like a residential refrigerator and 40" televisions, it is stingy on power usage meaning we can dry camp without running the generator every day. I only have to deal with one motor rather than two (I can't imagine not having a toad).
Yes, I am well aware of the trade offs of not having a motorized RV. We don't have as much storage space. That would be my major concern with full timing in a trailer, but there is just one of you so it could work. You will have to really think if the units you look at have room for all the gear you will need. You do need to learn to back a trailer. It is more a matter of patience and practice than rocket science. Both of us have learned to do it, my husband when he was 12 (farm boy) and me when we bought our first pop up 30+ years ago.
I think pretty much all RVing forums are primarily populated by Class A and C owners, so that is the viewpoint that you see more often. At the rallies I have attended, we are generally one of two trailers with a few dozen Class As. That doesn't mean trailers are bad, it just means that most full timers done have them. Yes, there is a reason for that, but it doesn't mean it is right for everyone. A Class A might be right for us in the future, but it just isn't right now.
