Bikendan, we went through this a few years back. Our Starcraft 21SSO was a great trailer but as retirement loomed we knew that we would be doing some long trips. While I loved my pop up and the hybrid, camping in the cold was not much fun nor was tearing down and setting up every day on the road.
We left the hoses with the hybrid. I did notice a need for a second set of lynx levelers and an extension for the sewer hose. Bedding is also something that we had to add. We used our sleeping bags before but now have a nice queen bed just like home. Other than that, you will know what you need soon enough. This isn't your first rodeo. Have fun on the road. I highly recommend retirement.
