Oakmont 390MBL Reviews


  • Beautiful rv inside and out

    2016 Oakmont 390MBL 

    Review Photo What I liked most: The mirror when you walk in or walk out. The storage behind the mirror for coats. Kids love the loft, it has lots of space and a big comfy mattress. The entertainment room has a nice foldout couch and a beautiful wood entertainment center with lots of storage for movies and games. The nightstands on each sides of the bed are nice for keys, wallet, phone etc. The TV can be seen from most seats in the main living area.

    What I'd improve: Put some power outlets closer to the night stands next to the bed.
