Re: Just bought our first RV
Hey Lori, welcome to the forum. You will need a Deep Cycle Marine/RV battery for your RV. If you want cheap, you can get one at Wal-Mart, Sam's Club or Costco for somewhere around $60 to $70 depending on what size you need. Most places want your old battery in trade. They recondition/recycle them.
You will need a white water hose, a water regulator, and possibly a water filter. Your best bet would to purchase those items from Camping World if you have one or a good RV parts dept. Get a Marshal brass water regulator, a water hose that has a flanged female connector and a water filter that is orange on both ends. The hose, regulators, and filter sold at Wal-Mart aren't very good. You will probably need some power cord adaptors that you can buy at Wal-Mart. Not sure if a "72" Jayco has a 20 amp or 30 amp power cord. you will also need a sewer hose. I use two 10 foot and one 5 foot section so I can reach most sewer connections. Last but not least get a box of 50 disposable gloves for connecting/disconnecting your sewer hose from the campground sewer connection. That's just a starter list. Everyone will have more to add or give you their idea of what's best. We all have our own opinions.
