Breaker Panel

[Simplified]

Hello to all, we just bought a 4092 BFL destination trailer and delivery is set for mid October. We won't be there but during the walk through I forgot to ask a few essential questions, I was just in awe of the unit. First where is the electrical panel located? I may be in plain sight but I might have missed it. Secondly is it advisable to support the bump outs, since they will be extended for about 4 months at a time. Also has anyone vented their washer dryer in the closet straight up through the roof or some other way, downward, under the stairs to the outside?

Thanks in advance.
