Higher end brands?

Lance and,Arctic Fox are two that come to mind. Airstream of course. But who wants to pay their prices.

It sounds crass but the more you pay the better the quality. Hence those that get high marks include Air Stream, Lance, Big Foot, Arctic Fox plus the eggs like Casita, Scamp etc.

TTs are built to a price point, so every brand has their high end an low end models.

The RV industry sells over 400,000 TTs and 5vers a year. The vast majority serve their owners well.

Unfortunately the constructions methods are quick and fast to keep the price down.

They are in the North West but look on the web for "Outdoors RV"

Oliver built in Tennessee. Custom builders as well such as New Horizon, Continental, Spacecraft mfg.

If you're after spending a lot, check out Safari Condo, now with a factory in the USA.

I'd stick with the Open Range if you're happy with it, I'm not sure what line of Open Range TT you have, I've had several Carriages over the years and the Open Range are built very similar. The Lance Lance Travel trailers are really nice too and they hold their value like a AirStream.

Yeah Airstream is out of the question for numerous reasons, space being one. Don't want custom, but just something that will last and feels solid.

Airstream and myself will never be on the same page until they take out the short bed and put in a full 80 inch bed. Too bad really.

I'm guessing you've seen Open Range is now owned by Jayco, and marketed under Highland Ridge.

With that said, I'll second the vote for Outdoors RV as above. We read floor plan as most important all the time, but a nice floor plan in a poorly constructed trailer would get old in a hurry when your spending that much money.

Spend some time looking at the construction. Us Southeast folks can really benefit from a true 4 seasons camper, even though we don't much need it in the winter. BTW, these things are heavy, but that's a good thing if you choose wisely.

Couple of old articles on Outdoors RV that might be interesting, via Northwood/Artic Fox connections:

Outdoors RV delivers first unit

I've read here, and other places of folks driving across the country to get their Outdoors RV camper. Must be something to it, or else folks just like a big adventure when buying a new RV.

Good luck!

Sometimes a used unit comes along, and wise buyers check them out. I am certainly happy with the quality of mine.

Check out Triple E Topaz

There were made in Canada until 2009 and are exceptionally well made.
