It has been a while and no suggestions were posted, so I will provide my limited knowledge. I own a 2018 Dutchman Kodiak Cub.
Dutchmen, Kodiak, Keystone, and Voltage have higher probability of a negative experiences. Often new ones end up spending many weeks being repaired.
Customer support is through Keystone. It has been unhelpful for me. They seam to excel at finding reasons not to cover under warranty. Any reason you can't prove is false beyond a reasonable doubt is a good excuse. Some advertising is deceptive.
The one you are looking at probably already has design and build issues corrected and so should provide a much better experience for you. Various parts have stopped breaking and falling off my 3 year old Cub.
I wish you good luck and happy trails ahead!
