The Northwood family of products and Lance usually tops the list of recommendations. Can't get anywhere near as bad as some other brands/models can get on quality and features, esp. on some ultralites. Getting a non-Lippert frame is a good idea and both Nash & Outdoors RV use the same in-house built frame and Lance uses a BAL/Norco Ultraframe. These brands also have good 4-season insulation, not available in others.
I would compare various features between other brands as well to see if anything is lacking in Northwood or Lance TTs. Have been to a number of RV shows and at the last one, I got talking to the Nash rep. Very impressed with the thought they put into them, like for example, a 2" drain outlet for the FW tank so you can dump it in seconds rather than waiting forever for a 1/2" PEX line to empty the tank.
But, on the Nash TTs I looked at, they had teeny weeny pass-through compartment doors compared to most other brands. An undersized compartment door like that would drive me totally nuts as it would be a lot harder to get stuff in and out. I noticed that KZ enlarged this door on the 2015 models of our TT to almost the height and width of the compartment - excellent improvement IMO.
It's the things you don't think to look at closely or think about functionally that can get you afterwards. When narrowing down, spend lots of time inside thinking about where you'd store things, is the TV in a comfortable viewing position, is the sofa (if so equipped) actually comfortable or just look like it is? Etc., etc.
One of my pet peeves is on upper and lower cabinets, they typically install blank plywood panels in some locations where there could easily be a door. Stuff ends up being out of view and difficult to get out. In some locations, there's an unusable void in cabinets and all they had to do is install a door. Another one is the lack of drawers on either side of a walk-around bed. Some TTs have them, but most don't. I just installed them in our TT and can't imagine not having them now. In a smaller TT especially, storage space is like gold.
What is the TV? If doing a lot of travelling and to hilly areas, even at 23-24', I would consider having a 3/4T. And if you get a heavier Lance or Nash unit, all the more reason to. We used to tow a 20' 5K lb TT with an F150 and it was awful on longer steeper hills like 6% and up. I'd also suggest an 8' bed (with canopy) as you can get a ton of bulky stuff in them.
