It's waaaay past time for my to give an update.
I looked at Diesel Pushers, Class A, Class C, 5th Wheels, and Travel Trailers. I listened to my girlfriend, as well as everyone here who took the time to reply.
I ended up going with a 2019 Forest River Grey Wolf 23MK. One Queen upfront, walk through bathroom, and kitchen and living space in the rear.
I have a lot to learn and relearn ... mostly trying to figure out the best way to travel light, and find a place for what I do need, PLUS ordering all the stuff I no longer have but *need*. My truck needed some work too, and I'll probably give it a suspension upgrade too, just for some added security.
I've been camping in it locally for almost two weeks and so far so good. The real test will be when I take it cross-country starting next week.
Thanks again everyone!
