What model Vision do you have? In our 2021 Esteem 27U, it is under the bed. Our bed is on a small slide, and when it is extended and the mattress lifted, there is a panel that can be removed and there is a ton (almost literally) of devices, wires, cables and floor penetrations, one of which is the inverter and one of which is the inverter transfer switch.
Which breaker is tripping? Under what conditions does it trip? (Coffee pot? Space heater? Roof A/C unit? Refrigerator on AC? Water heater on AC?). On our coach the top breaker is a 30A and it is the incoming "main" breaker. The fourth one down is a 15A and it is the "inverter" breaker. The bottom one is a 15A and it is the "GFI / Bath". Which one is tripping?
Which fuse is "blowing"? I would not expect any fuses to be involved with any of the AC outlets in your coach. That is a puzzle!
Other than that, I hope you enjoy your coach, a ton!! They are great fun!
