Welcome to IRV2
You will not find a more helpful or informative RV website anywhere.
It has been several years since we owned a travel trailer and we are now on our third motorhome. From our experience owning/using RV's since 1975, I believe it is always better to find a higher end gently used rig than paying for a new one. You avoid the pretty steep depreciation associated with buying new and, in many cases, the first owner has been through the often frustrating process of getting the new unit de-bugged.
Now the challenge is finding a used rig that has been well cared for and maintained to your expectations. I am always amazed at how much some folks will pay for a nice, new RV, and then let it go to pot in just a few years. Take your time and good luck in your search.
Hoping your enjoy whatever you end up with.
