If its a RV park like a campground , they are full time businesses , reservations , hospitality , clean up camp store .

Long term I would definitely store extra appliances and stuff in the basement.

I'm sure they're available at Home Depot, Lowes, or other hardware stores.

I'd love to have a place to store a couple of stoves and fridges so I could do a quick change out and then after I have a few bad ones have someone change out that bad $10 part.I have repaired some of my own high end appliances.

This is getting into the specifics of cameras, to record either on the action (such as opening a door or motion detection) or continuous 24/7 monitoring, which is stored on a DVR.Cameras are an integral part to any security posture on a property, whether it's a commercial property or residential. 

Have discovered  that the big Salvation Army retail store which is next door has gone out of business. 

For folks like plumbers, etc. go to a plumbing supply (not big box) store.

(Yes I stored the china on the closet shelf, kitchen was small.)The manager came and saw what had happened.
