I've used a 20' travel trailer for over 10 years, ( bought it used then) and left the ratwife and kids at home. With the shorter outages, you gotta do what you gotta do. I keep it loaded with the outrage clothes and supplies. I've learned over the years to use PVC piping (cut to size each time) for the septic drain rather then the cheap blue accordien tubing. I used heat tape on the water hose with that foam tubing rather then fiberglass fluff and wrap. Foam rubber panels cut to size for the windows with plastic for the winter and rock-salt as a cheap way to keep the drains flowing in the winter. Beadboard panels cut for a skirt also. I look for a shady spot for summer time. A plus is two trees nearby close enough to string a hammock. I never bothered with satellite TV cause with long hours, who has time. DVDs are nice though, entertainment on demand. The new technology of cell phones has been a real benefit over trying to hook up a wire line each outage and the hassle with local bells. If the outrage is going to last more then a month, I've found mobile-home parks (utilities separate) cheaper then the convience of an RV park.
Gotta have Duct Tape, silicone rubber, hand saw, hand shovel and contact cement. Trust me.
