Hunter100, if you are still looking ...
With your past experience with trailers/motorhomes, you probably realize that EVERY RV you consider is a compromise. There is no such thing as a perfect one. So you have to figure out what advantages are most important. And what you can't live with.
I started with a '67 Ford F250 with a camper. Versatile, since I could unload and have a truck for other purposes. When I thought I could afford both, I got about a 23 foot motor home. It was a foot longer than the camper setup, two inches wider, the same height, and seemed to have about twice as much interior space. But since it wasn't much bigger than the pickup/camper, we could stop pretty much where we wanted, and I don't mean just camping. My wife would say, "Look! Let's stop at that antique store!" and I would pull right in. We got rid of the MH because it aged out before we did. And I'll never have a rig again that's so old that is has a carburetor instead of fuel injection. You ever have to fiddle with all 13 adjustments on a 79 Dodge ThermoQuad carb? If you messed with one, you had to re-do them all.
We retired some years after the motor home adventures, and the wife informed me she was not sleeping on the ground anymore. What's more, she said she was not about to re-make the bed every single night and morning. So I had new parameters. Including, that I needed something I could tow with the 2008 4Runner I just bought. It will go anywhere and then some, once the trailer is parked, and is very versatile for other uses.
This time around I too was intrigued by the Hi-Lo concept and really appreciate the better gas mileage. And I thought, "How much better is it to have a tow vehicle you can unhook and go driving up into the Idaho mountains where no motor home would ever go?" But, big compromise: I can't just pull into that antique store on a moment's notice. Now, I have to find some place I can park a rig that's twice as long, maybe go around a block or two and walk to the store, maybe can't find any place at all available to put this thing. So you give up one advantage for another. A whole different life style on the road.
But OK. I looked at some Tow-lites and then a Classic. Appreciated the greater storage and some other nicer details about the Classic. Looked at models under 20', but there was no way we could leave the bed set up and still have a table to eat at, and I was not keen on just a single axle. The models longer than 22' were all too heavy for the 4Runner to pull, even with the load-distributing hitch I installed. I thought something 2001 or newer to get the aluminum frame, but it seemed like they were all 24' or 25' or greater; too heavy. I ended up with a 1999 22' Classic, with a steel frame. You can leave the front couch made into a bed and still have a table to eat at. The couch conversion is not as comfortable sleeping as I'd like, but is tolerably good with a decent foam cover.
Notice all the compromises in the above? No matter what you do, you will have your own list of compromises.
And of course, the Classic is a compromise over the Towlite not just because it's heavier, but because it's wider. Which means a little less convenient to drive around with, and you need wider mirrors. Which I just get by using the McKesh mirrors. A guy on another forum said he got rid of his McKesh's because the mount crushed the rubber seal in the window of his 4Runner, but I added a little piece of oak to each one and never have that problem. More compromises ...
Well, this post is way too long, but maybe gives some food for thought for some.
