Yep, as many have written, they are still being made. We were considering one made by Nash. Related to Arctic Fox (also a Northwood). Didn't get as far as going to take a look at one, however. Decided on going with a Lance with a slide. All Lance trailers have slides.
We also looked at a Jayco without a slide at a dealership.
http://www.jayco.com/products/travel-trailers/2015-jay-flight-slx/floorplans-and-prices/We have just returned from two weeks camping trip in Alaska in a rented Springdale 198 TT without a slide. A very well made & constructed trailer, it seemed to be. Floor plan was workable, but it didn't have a queen bed. It had a full bed with a bunk above it in side an alcove which made it difficult for me to use it. Almost impossible for to get out of it with someone sleeping with me. Not bad just with me using it, which is what we had to do.
Springdale West Coast Models None without slides listed on East Coast Models.
Couldn't get the Nash site to open this morning, but found this demo video featuring a Nash, but not the one we were interested in, which had a queen sized bed. This one has the same floor plan as the Springdale we had in Alaska.
Good luck with your quest.
