I will tell you this much..... You will get an array of answers from they are awesome, to they suck.... Truth is, they are built in Indiana by the same work fork force that builds 90% of the RV's...
My first Redwood was a 2016 and it came with some minor issues, all of which the dealer handled... my present Redwood is a 2020 and just like the 16, it came with some minor issues either at delivery, or after usage, all of which the dealer fixed.
I strongly believe that YOUR dealer can make or brake you feelings with any manufacturer.
After attending the last RV show here, I walked away saying to my self, I love my Redwood.... You have to have thick skin and a knowledge and ability to just suck it up and fix somethings yourself.
I camped next to a guy 2 or 3 years ago that had a brand new DRV, HE HATED IT... the list of things that were wrong or broke was as long as my arm, and he showed me some of the workmanship...
While at Lazy Days picking up u buddies new Solitude, I was chatting with a service technician that was working on a brand new Rivestone... he told me to NEVER BUY a Riverstone. they had more issues than any other brand they sold. When we were getting our recent "2020" we were also looking at Landmarks, that is until we looked at them in person and walked through several.
Good Luck with your decision.
