I also have a 2019 990 that we have had for a little over 3 years. Only had to wait 5 weeks from when I ordered it to when I picked it up. Times have changed a bit yeah? Quality is fine and have had no issues. I have been in Northern Lite's, Bigfoot, Adventure, and Host campers just to pick up any ideas or mods and the 990 is the one to beat for our usage. Having a slide out makes all the difference in the world and never feels like your close quarters. Just an FYI I paid 32k for mine. Didn't get the $4000 Genny and added one for $600 when I got it home. Would purchase again in a heartbeat.
Good luck in your search.
