Having RVed for 40+ years and owned/rented many units, we have some experience.
First, the bed is very firm. I see others called that out. We bought 4 king pillows to soften it up and left them behind for others to use.
Second, upon arrival we noticed a musty/moldy smell which we couldn't place. On our second night, we were woke by the CO2 monitor going off. It turned out the rain that night came in through the wall by the door and setoff the monitor. Looking closer, the carpet was all soaked and black. That was the smell before... soggy carpet! The unit needs TLC. We left early with no refund.
