Our 2020 Solitude 2930RL has had issues. Nothing I couldn't fix myself but I pack a lot of tools. Bad wiring, trim and cabinet panels falling off, door hardware, leaking PEX piping, heater ducts with leaks... If we had to drag it to a dealer for every issue I'm not sure how many nights we would have slept in it over the last year.
Honestly I don't know if things are any better with other manufacturers in the price range of the mainline manufacturers.
In the nexts 2-5 years we are going to pull the plug on a New Horizons and have a bigger role in the manufacture of our FT home and hopefully a trailer built by a company not 100% driven by profit via the number of units they can pump out...
