Some Newell Ownership Newbie Questions

[Rich Franklin]

We just purchased an 1986 Newell and have a couple of "newbie" questions:

1) How do we remove and install large items like the sofa, washer/dryer combo and mattress? They are obviously too big for the from door.

2) It has already been winterized and is sitting in our drive way. The inverter is presently on and the switch on the inverter indicates it's not for turning it off. When we flip that switch the inverter still has a humming noise.

3) Is that ok to leave for a month or two or do you disconnect the batteries, etc?

Thanks in advance!
