Toy haulers are not the optimal trailers for tastes of full timers, the "garage" makes the living space a bit skimpy. Full timing is more a state of mind rather than a rig, I've known couples who can't stand each other for more than a week in a half a million bus and I've seen persons full time in a van conversion.
We started (42 years ago) in a tent, then went through 11 foot slide on, 32' fifth, 36' fifth and now a 40' fifth. Other than the tent we could spend long expanses of time in any of them, but it was the 40 footer that gave me (us) the "feeling" that I didn't need the house. We did 11,000 miles in it over 4 months three years ago.
If you need to work on the road you will need a "work space" (computer space) away from the main living area and a "real door" that you can close. In my instance I have a computer desk in the bedroom that I can close off.
You are starting pretty young (younger than us), congratulation, I don't look at the various RV's I had as "mistakes", it was just phases of what I could afford at the time and what served our purpose at the time. Although I admit that the 36 foot Corsica (bought very cheap new at an auction)
was an absolute piece of crap and literally fell apart after few years. The RV industry still manufactures lot of glitzy crap so you need to educate yourself on which rigs are more suitable for fulltiming vs. weekend RVing
You might want to start your "education" with Lippert. https://www.google.com/search?q=lipp...hrome&ie=UTF-8
