Must buys for our new to us travel trailer?

Credit cards and a Walmart or Camping World along the way. We treat our RV as a second home, it is stocked as such. Most of the items you will receive from the dealer in their so called starter kit will be of substandard quality, those items will need to be replaced early on to avoid mishaps. There are lists galore available under Beginning RVing forum, it takes a bit of time to figure out essential and non-essential items which will differ from person to person. Good luck and here's hoping that your RVing experience is all you expected it to be.
