Prep the RV for long-term use. Clean your water tanks and water lines, and flush your sewer system, to get ready for steady use. Make sure you RV is in good working order. Have your electrical and heating systems checked by a professional, if possible, as they will undergo a lot of wear and tear while you're living in the RV, and you don't want a heater going out in the dead of winter. Deep clean the RV's kitchen, bathroom, and other areas.
Pack your RV with all the items you will need for long-term living -- all of your clothing, bedding, books, media, and other personal items. Be sure to use all available space in the RV's storage areas, but take care not to over-fill the compartments. You will need to get in and out of those areas daily so be sure to keep things organized.
Sell all items that will not comfortably fit in your RV, or place them in a storage unit. You can sell furniture and other large items online at Craigslist.com, while the smaller things like clothing and household items can be sold in a yard sale. Another option is donating your unwanted items to a store like Value Village or Salvation Army. Each company has several stores in Nova Scotia.
Make reservations for a long-term stay at an RV or mobile home park. The larger cities like Halifax and New Glasgow have many mobile home parks that may be willing to take a long-term RV. If you'd like to try living in your RV at an RV park, try the New Glasgow Highlands Campground and Camp Cabins, or Woodhaven RV Park of Halifax, both of which accept long-term guests, and have long-term rates. Check with the campground host about getting one of the best locations on the lot, since you'll be staying for a long time. Reserve a space for several weeks or a month starting in the spring if possible, to get a feel for what RV living is like.
Drive your RV to the trailer park. Since you are going to be staying a while, consider elevating your tires as you would if your RV were in storage mode, to reduce the wear and tear on one side of the tires. Set up your electrical and sewer hookups.
Schedule regular flushes of your sewer system, as it will be getting a lot of use.
Maintain good relations with the campground or park owners by keeping your campsite tidy, with minimal outdoor accessories. Pay your rent on time, and avoid having rowdy parties or fights at your campsite.
