We have a 2025 Avenue 25RK which is almost the same thing, here are few things to watch out for.
1. Leaking outside shower quick connect, the Dealer replaced 3 times but the replacements are defective, looking for Alliance to find alternative. Make sure you test this during the PDI
2. Bent /kinked Sewer hose carrier, caused by the rear kitchen gray tank hanging to low and also leaking
3. Rust coming from the ladder grab handles where it connects to the roof.
